The PA1001 and PA1002 based MPX stage of the SX-1980 are the same as in this tuner. Its new-dimensional PLL (Phase Lock Loop) multiplex circuit improves the multiplex function considerably and is based on an entirely new principle. The TX-9100 uses discrete transistors in its output stage (no op-amps) and has a smooth, powerful sound that some prefer to that of later Pioneers. The mixer is balanced. You can pause and rewind live TV at the touch of a button allowing you to pause for a cup of tea or answer that door. The TX-9800 has exactly the same RF front end as the TX-9100 and TX-9500/TX-9500II, with differences only in the IF and audio circuit areas. From a technical standpoint, however, the TX-9800's complex crystal referenced oscillator sets it apart from those other Pioneers. In the first stage dual gate MOS-type FET is used, while the second stage features junction-type FET. "Performance characteristics aside, the TX-9100 is a superb example of the application of advanced circuitry to music enjoyment. The automatic gain control of the AM section is excellent. Outstanding FM front-end section with dual-gate MOS FETs, 5-Gang variable capacitor and two-stage RF amplifiers. I never realized that until I spotted a mysterious FET and resistor near the stereo decoder in the schematic. The harness manufacturers made their install harnesses for Nissans first, so they didn't bother coming up with a different version (or even a different part number) for Subarus. Capture ratio is also distinctive, measured at 1 dB (IHF). David adds that the TX-9100's quieting curve is steeper than that of the Yamaha CT-7000, and comparable to the Kenwood 600T's. In stock form all of the ceramic filters are 280 kHz. After I carefully reset the alignment, I was impressed that CCTS was able to slightly improve it. Heathkit 6-stage limiter in FM IF section with all-stage differential monolithic ICs. The FM IF has 7 ICs with differential amps, 4 ceramic filters (with 2 elements each) and a wide-band linear detector to pinpoint selectivity at 85dB or better and beef up the capture ratio to 1.0dB (IHF). Subscribe to receive our latest thinking directly to your inbox. Not only are they better than the stock mylars, they correct the de-emphasis time constant from 62.8 µS, in stock form, to 75 µS. See how one F-91 sounded compared to other top tuners on our Shootouts page, and read our panelist David "A"'s Ricochet. Other features are equally significant. The narrow path has 5 ceramic filters. "Designed to play a key role in obtaining optimum reception even in areas of weak signals, the front-end section of the TX-1000 provides excellent sensitivity and signal-to-noise ratio as well as outstanding image rejection, cross-modulation rejection and spurious signal rejection. Large signal meter and wide linear FM dial scale for easy tuning. Read on to learn why it's the finest component of its kind for your stereo money. Our contributor Scott reports: "The TX-1000 is a well-built unit with a large power supply. Additionally, FETs are also used in the mixing circuit, which complements the stabilized Colpitts-type mixing oscillator. Audio Research When/If I hear more information, I will post up on the message board. Two-step FM muting switch. The new Murata 230's make a big difference in signal strength - about 1/2 notch improvement on the signal meter. Inside I found what at first appeared to be a basic tuner circuit, with two RF tuned circuits in the signal path, two IF filters (280 and 180 kHz), and a single-tuned quadrature detector. A very important addition to the Pioneer line of quality stereo components. For even greater performance, the TX-8100's IF section uses new IC and phase linear ceramic filters to achieve a selectivity ratio of more than 80 dB (IHF) and capture ratio of 1 dB (IHF). The construction of the unit makes it very easy to service and modify. Our contributor Roger says the TX-7800 only has two gangs for AM, but switching to Narrow mode ups the selectivity to 50 dB vs. 15 dB in Wide mode (according to the published specs). See how our panelist Jim thought one F-90 sounded compared to other top tuners on our Shootouts page. Recent Updates Independent AM, FM output level controls. The TX-1000 is a handsome stereo component with stylish front panel and natural wooden case. The TX-9500II has 5 gangs and a very unusual configuration of filters: an LC filter and an SAW (surface acoustic wave) filter for the wide IF bandwidth mode and 5 normal 3-pin ceramic filters for narrow mode. The TX-D1000 is similar to the Phase Linear Model 5100 Series Two tuner (which was built by Pioneer) in most respects, except that the TX-D1000 tunes in 25 kHz (.025 MHz) increments, allowing one to detune slightly to avoid adjacent channel splatter. The TX-7500 is very common on eBay; almost any sale price is possible up to $100, but most sell for $40-60. google_color_url = "008000"; Maybe the full service manual or the data sheet gives more details. The TX-7100 usually sells for $40-70 on eBay, but almost anything is possible ($1.00 in 5/07, $18 in 4/08, $101 in 4/09). See how one TX-9500II sounded compared to other top tuners on our Shootouts page, and read David "A"'s Ricochet. With some work, the F-9 is really a bona fide hot tuner in every respect. Pioneer TX-7500 (1976, $250, photo) search eBay Multipath output terminals. The TX-9500II may be the high-water mark for Pioneer other than the Series 20 (F-26 and F-28) line. Occasionally, someone will overpay for a TX-6800 ($66 in 2/08, $82 in 6/08) when he doesn't know he can get a TX-7800 for that price. It has 4 gangs (vs. 5 for the TX-9500II) and wide and narrow IF bandwidth settings like the TX-9500II. Our contributor Bill Ammons says the TX-7100 "has a good RF front end, but with only two filters and one IF gain stage, it limps along. 11 comments. That is, to a point. Quite a mixture. Outstanding FM front-end section with dual-gate MOS FETs, 5-Gang variable capacitor and two-stage RF amplifiers. In the TX-1000 the IF section circuitry employs four ICs and a pair of crystal filters and IC filter. This circuit removes unwanted pulse noise such as that from a weed eater. Our contributor PZ says: "I find the F-91 to be an interesting unit. The front end, for instance, features an ID MOSFET to improve reception. The process for finding out a car radio code differs from one make to the next, but you’ll generally want to start … The TX-1000 is a handsome stereo component with stylish front panel and natural wooden case. Bob comments, "It apprears to be very similar, if not identical, to the 'active tracking' used in the H/K Citation 23." The wide/narrow switch and filter configuration distinguish it from its virtually identical predecessor, the TX-9500. Our contributor Bill Ammons says, "In the wide mode there is one ceramic filter followed by a tuned 10.7 MHz LC circuit. Sale prices for the TX-9500 on eBay are very inconsistent, as with many Pioneers, and the averages dropped noticeably from $125-185 in 2004, to $65-110 in 2005, to just $45-100 in 2007, but $80-130 seems to be the current range. Additional information on the TX-9800 is available at classic-audio.com. Pressing a button momentarily displays signal strength as a single digit. We believe the Pioneer brochure description read substantially as follows: "An advanced professional AM/FM stereo tuner, with unique P.L.L. The TX-9100 is one of the few tuners with a front-panel headphone jack with volume control. The kid forced to wait on you will look at you like you have Three Heads!" The construction of the unit makes it very easy to service and modify. 2 Press RESET with a pen tip or other pointed tools. Pioneer TX-9500 (1976, $400, photo, rack mount, schematic, alignment guide, schematic left, schematic middle, schematic right) search eBay Even in signal-weak or signal-strong areas your station comes in clean and fresh. The linear design is not only easy-to-read, but also brings all stations closer together for easy tuning. There is also a special PNS (Pulse Noise Suppressor) built-in to the TX-9100 that cancels irritating pulse noise such as automobile or motorcycle ignition noise. Capture ratio is also distinctive, measured at 1 dB (IHF). Its getting quite painfull, have to adjust the base again and reprogram my stations only to lose them, now I dont even bother. Other controls include separate output level controls for AM and FM, an MPX filter, and a muting switch offering two levels of muting or off. OK appears in the display to indicate that the receiver has been reset to the factory default settings. Watch CNN streaming channels featuring Anderson Cooper, classic Larry King interviews, and feature shows covering travel, culture and global news. Phase-linear ceramic filters in the FM IF section for excellent selectivity and phase characteristics. And even without an amplifier you can still listen to this unit through headphones plugged into the headphone jack. In our favorite TX-6800 auction in 11/02, the "winner" paid $60, just nosing out another dummy who bid $59.99 (a great way to bid if you're a shill bidder, or just trying to lose by a penny). The sockets will eventually hold a pair of Bill Ammons's amplified filter boards. These three methods .... new pioneer radio, no memory settings - When I set clock ,radio stations, etc on this radio it sets at the moment. "The FM IF section determines the tuner's effective selectivity. They are not used in a slightly turned off mode. The high was $137 in 2/05 as two dummies fought it out. There seems to be some truth in this, since it took about three weeks for the sound to smooth out and become listenable. There is also a special PNS (Pulse Noise Suppressor) built-in to the TX-9100 that cancels irritating pulse noise such as automobile or motorcycle ignition noise. Offering what is certainly one of the finest FM sensitivity ratings ever built-in to a tuner, the TX-9100 is an incomparable blend of solid state circuitry and design, the most advanced unit of its kind available today at any price. The new Murata 230's make a big difference in signal strength - about 1/2 notch improvement on the signal meter. Introduction (In the KT-7500 and other dual-IF tuners, a wide-bandwidth ceramic filter may be left in the wide IF mode for great sound on local stations while narrower filters can be installed in the narrow IF mode to improve selectivity for DXing.) In The Future of the New, artists, theorists and professionals working the art field reflect on the role of the arts in a world that is speeding up and changing through the joint forces of globalization, digitization, commodification and ... Dynaco Pioneer TX-7100 (1973, $200, photo) search eBay Resetting the car stereo Resetting the Pioneer car radio is a very easy fix for minor problems in your audio system. Output level controls for AM and FM are independently adjustable. I suspected that this might be the classic Black Gate sound, since these caps are notorious for taking a very long time to burn in. The distortion in wide was 0.015%, narrow 0.02%. I don't understand how they do it, but apparently it was so complex to build and keep aligned that they never used it again in any other model." The unit is hard to modify because it is so well shielded, top and bottom of all circuit boards. The Pioneer TX-9500 has a new streamlined look, logically-arranged switches and controls, and a scientifically-designed tuning system that makes it all look so easy. The audio output is discrete. Turning off the FET slightly so that R ON is 10 K or so increases the de-emphasis to a few hundred microseconds. The TX-9800 has 5 gangs and 5 filters, one for the wide IF bandwidth mode and 4 for narrow, and is solidly built. Pioneer F-5 (1981, $225, photo) search eBay See how one stock TX-9800 sounded compared to other top tuners on our Shootouts page, and read David "A"'s Ricochet. After a while, the foam material breaks down, and it becomes very hard to get the presets to change. Following the lead of the mods on TIC, I upgraded the power supply with Schottky diodes and new electrolytics and replaced all electrolytic and tantalum caps in the audio signal path. There is a headphone output jack with an adjustable level control so that you can enjoy stereo listening with the tuner only. Ryan adds, "This is one of the few stock tuners that I have seen to use audiophile grade parts where it counts. But I would have to add two hours of bench time just to service this one. "I wondered what the CCTS function did. There's a page on the TX-6200 with photos, specs and brochure excerpts on the Stereonomono website. In any respect, the F-28 is an absolutely remarkable tuner - a true sleeper in my opinion." Also (on HU in some Foresters only) subwoofer output, 20-pin connector for power, speakers, SWC, and CAN. Pioneer TX-8500II (1977, $300, photo, block diagram, schematic) search eBay Most Subaru radios have a standard "Motorola" style antenna connector (big, round coax). Our contributor Ryan measured an F-99X extensively and reported that it works very well, providing low measured THDs, as well as very low intermodulation. The TX-1000 is a handsome stereo component with stylish front panel and natural wooden case. And much more. The unit is hard to modify because it is so well shielded, top and bottom of all circuit boards. Simply flicking the noise filter to the ON position will correct high-frequency MPX noise which is often created during reception of FM stereo broadcasts. Additional information on the TX-9800 is available at classic-audio.com. I currently am using three Murata 230's and two Toko 110's and find that it has amazing selectivity with that combo. Pioneer TX-9500 (1976, $400, photo, rack mount, schematic, alignment guide, schematic left, schematic middle, schematic right) search eBay And in Ray's shootout between the TX-9800 and the Sony XDR-F1HD, "the Sony would easily find a DX candidate and then, with much tweaking, the TX-9800 would get it also but not as quietly. FM Multipath output terminals. The tuner uses a 2SK241 RF amp, HA11225 IF amp/detector, AN7470 stereo decoder, LA1247 AM chip, LC7217 PLL, and M5223 varactor driver op-amp. The F-99X was Pioneer's update to the earlier F-90, and made a number of improvements that contributed to better specifications and performance across the board. So the bulbs effectively "see" a range of 2 volts (dimmest) to 12 volts (brightest). The F-90 is very common and usually sells for $40-100 on eBay, with a low of $25 in 9/08 and a bizarre all-time high of $245 in 5/09 when a clueless bidder hit the "Buy-It-Now" button. In an attempt to adjust the centering meter, the upper and lower frequencies at which the stereo beacon would light were noted, the tuner set twixt those points and the meter centered there... seems to work OK. For anyone still reading this drivel, the TX-6200 had the right stuff for good sound." The 4 ceramic filters in the IF are followed by a ratio detector. More recent highs were $368 in 2/08 and $299 in 12/08. In Android settings, tap on a device’s name, then Unpair. In the TX-1000 the IF section circuitry employs four ICs and a pair of crystal filters and IC filter. The dealer informed me that this is extremely rare and makes this tuner highly sought after for high-end collectors!" Our contributor Bill Ammons says, "In the wide mode there is one ceramic filter followed by a tuned 10.7 MHz LC circuit. It is reasonably selective for a single-bandwidth tuner and has good to very good DX capabilities for a 4-gang unit. Our contributor Gary adds, "The TX-9500II does the best job to date of picking out weak stations in narrow mode. Fixed and variable output level controls.". Roksan I suspected that this might be the classic Black Gate sound, since these caps are notorious for taking a very long time to burn in. And because output terminals of the TX-8100 are both fixed and variable, it is possible (by utilizing the fixed output) to direct-record from the tuner by bypassing your amplifier. Rotel Our contributor Bruce reports, "I recently bought a TX-9500II that needed some work, but sounds very nice. Other features are equally significant. The headset is reset to the factory settings. I added some BUF04 output buffers along with a small transformer and LT1085/LT1033 regulated supply, which really opened up the sound. Double-Action FM Muting circuit with read relay. This book is based on an expert group meeting entitled 'Male Roles and Masculinities in the Perspective of a Culture of Peace', which was organised by UNESCO in Oslo, Norway in 1997, the first international discussion of the connections ... Both IF paths go through 5 stages of bandpass limiting similar to the TX-9500, but a pair of multiple-section LA1222 chips are used instead of the five single-stage limiter chips in the TX-9500. The S/N ratio is also improved, and sensitivity is an excellent 1.7 μV. And even without an amplifier you can still listen to this unit through headphones plugged into the headphone jack. Its front-end section employs dual gate MOS-type FETs in the RF stage and mixing stage, coupled with a frequency linear 4-gang variable capacitor, the entire package adding up to sensitivity rated at 1.8 µV (IHF). If you have been seeking an AM/FM stereo tuner offering the rare blend of advanced electronics plus a practical price, the TX-8100 is for you. Fixed and variable output level controls." Linn Complete with the very latest design components and transistors, the TX-1000 provides all the requirements that the audio enthusiast demands in a tuner - and then some. Here's a follow-up from Brian: "I just bought an F-90 for a friend. In narrow, the signal routes through the wide filter and consists of 3 more ceramic filters and one additional tuned LC. Then comes a double-tuned stage followed by another RF stage (never a good sign - this means they were going for a good sensitivity number at the cost of IM [intermodulation - Editor] problems). The linear design is not only easy-to-read, but also brings all stations closer together for easy tuning. Sensitivity is pretty good. About eBay Even in signal-weak or signal-strong areas your station comes in clean and fresh. The DMOS front end is very overload resistant and the double-balanced mixer performs very well also. See how one stock TX-9800 sounded compared to other top tuners on our Shootouts page, and read David "A"'s Ricochet. I wonder if possibly the team listed on the patents was disappointed that this tuner ended up being sold as mainstream item, versus being packaged better and touted as the breakthrough high-end unit it was." The filters are quite easy to get to. Actually, the TX-7500II, 8500II and 9500II also have the little sliders, but none of us at TIC ever thought they were even worth mentioning, let alone something that would cause a tuner to be "sought after." As with most Pioneers, sale prices for the TX-9500II on eBay are very inconsistent, although the TX-9500II tends to sell for more than the TX-9500, on average. ", Our panelist Bob adds, "I dragged out the TX-9500II and gave it a total alignment. So even with one bar lighted on the meter, one gets decent stereo reception." Hitachi Both AM and FM have separate output level controls. At the bottom left corner of the main board are new polypropylene de-emphasis caps. I also upped the power supply and bypass caps. Esotec The result is a constant performance unaffected by temperature, humidity or age and ideal selectivity characteristics of over 70 dB and a 1.5 dB capture ratio. In the Pioneer SX-1250 receiver, which goes for big bucks on eBay, the HA1137 is the chip used in the main signal path." Pioneer TX-6500 (1977, $175, photo) search eBay Pioneer has employed "phase-linear" ceramic filters in the IF section, coupled with a 6-stage limiter by monolithic ICs with differential amplifiers. It does, however, have an annoying combined "Muting On/Stereo" and "Muting Off/Mono" switch that prevents one from choosing to listen to a weak signal in slightly noisy stereo. Nikko The TX-9500 has exactly the same RF front end as the TX-9100 and 9800, with differences only in the IF and audio circuit areas. The TX-1000 usually sells for $25-40 on eBay, with occasional overpayments when an ignorant bidder seems to think it's comparable to a TX-9500. We can't figure out why this seller thought tuners are such rare pieces of equipment, and in any event rarity does not equate to quality. Double action FM muting with read relay. This unit had some really groundbreaking circuits that worked very well. Our contributor PZ says: "I find the F-91 to be an interesting unit. In narrow, the signal routes through the wide filter and consists of 3 more ceramic filters and one additional tuned LC. This unit had some really groundbreaking circuits that worked very well. It does seem to cut out a bit of the highs now on narrow, so I will replace the 110's with Murata 150's as soon as my backorder comes in. Pioneer TX-6500 (1977, $175, photo) search eBay Fanfare Not only are they better than the stock mylars, they correct the de-emphasis time constant from 62.8 µS, in stock form, to 75 µS. The TX-7500's single-bandwidth IF stage consists of 3 ceramic filters and one gain stage. Outstanding FM front-end section with dual-gate MOS FETs, 5-Gang variable capacitor and two-stage RF amplifiers. In the first stage dual gate MOS-type FET is used, while the second stage features junction-type FET. Pioneer TX-8100 (1973, $250, photo) search eBay The first edition of this book was the first text to be written on the Arena software, which is a very popular simulation modeling software. The TX-9500 uses discrete transistors in its output stage, rather than op-amps. The MPX outputs are buffered by a PA1002 which appears to be a Pioneer quad op-amp with some extra function that is not clear from the schematic. The TX-6800 usually sells for $20-30 on eBay. If the signal was really weak, i.e., less than 18 dBf, the Sony would be totally deaf and the TX-9800 would know it was there. The TX-9500II is built a little better, they deleted a bunch of stuff in the TX-9800 but added the crystal tuning. The F-91 was part of Pioneer's "Elite" series. The shields for each section that are present on all TX-9100s, all TX-9500s and most TX-9500IIs (ones that I have seen, anyway) are gone in the TX-9800, and the TX-9800's parts quality is worse overall." In the IF the main signal path has an 8-pole LC filter followed by a SAW filter. The TX-9100 employs a 5-gang variable capacitor and low-noise dual-gate MOS-type FETs in its FM front end, resulting in a 1.5 µV (IHF) sensitivity. Both of the IF filters are GDT flat group delay type for minimum distortion. A FET in each channel is used as a variable resistor with the de-emphasis network that follows the FET. The TX-1000 is a handsome stereo component with stylish front panel and natural wooden case. I think it may be the best deal in tuners if all you want is performance." I modified it by taking out the five Murata 280 kHz filters in the IF section and soldering in sockets to accept new filters. With two satellite cables connected to the unit you will be able to either record one channel and watch another or record two channels while watching a previously recorded programme or a programme from the On Demand service. Harmonically rich, full and with quite good low end extension and spatial portrayal - polite and lifelike." It is connected before all the limiters so that the meter does not saturate too quickly. Toshiba In addition to the TX-6200, other examples of this that he found are the Fisher FM-2310, Harman/Kardon TU615 and Realistic TM-1000. From a technical standpoint, however, the TX-9800's complex crystal referenced oscillator sets it apart from those other Pioneers. Large signal meter and wide linear FM dial scale for easy tuning. Our contributor PZ says: "I find the F-91 to be an interesting unit. Additionally, FETs are also used in the mixing circuit, which complements the stabilized Colpitts-type mixing oscillator. Our panelist David "A," who believes that many Pioneer tuners are highly underrated, reports: "I bought one TX-9100 recently for $10 mint and it blew away every [Yamaha] CT-7000 I have tried! There seems to be some truth in this, since it took about three weeks for the sound to smooth out and become listenable. The TX-9800 has 5 gangs and 5 filters, one for the wide IF bandwidth mode and 4 for narrow, and is solidly built. The MPX chip is a PA1001. Our contributor David Rich describes what's inside: "Same front end as TX-9100. This little brother of the TX-9800 has 4 gangs and 3 filters, like the Kenwood KT-7300, but its performance is stunning: more sensitive than a modified Onkyo T-9090, and just about as selective as the T-9090 when modified with one 110 kHz and two 150 kHz filters. I would also note the complete lack of high blend, which could be a big annoyance factor. This circuit removes unwanted pulse noise such as that from a weed eater. In stock form this model performs very nicely." We don't know much about the rare 4-gang TX-7500II, which can sell for $40-100 on eBay, but it's supposedly pretty good. After I carefully reset the alignment, I was impressed that CCTS was able to slightly improve it. Improvements extend to other circuits of the tuner as well. There is also a special PNS (Pulse Noise Suppressor) built-in to the TX-9100 that cancels irritating pulse noise such as automobile or motorcycle ignition noise. Low-noise junction FET in FM front end. The F-91, like Pioneer amps and CD players, is designed based on our anti-vibration concept to damp harmful resonance and vibration for improved sound. Low-noise junction FET in FM front end. Wow, it was not easy. Nikko A second mixer is needed to produce the low IF needed for digital direct decoder chip. The scheme is based around a variant of the analog multiplier multiplex, and works by multiplying the output of the pulse count detector with a 38 kHz sinewave generated by a tuned circuit. "The FM IF section determines the tuner's effective selectivity. Both units have a variable output option controlled by a pot operated on the faceplate. MOS-type FETs in the front-end, an IF section featuring ultra-sharp crystal filters and ICs with outstanding limiting effect provide unsurpassed capture ratio and selectivity. 1 kHz stereo THD was about 0.15%. Then the antenna amp will be 'on' (or the motorized antenna will extend) whenever you turn the ignition key to ACC or ON. Our contributor Bill Ammons adds, "The TX-9100 is not a bad-sounding unit, but the measured numbers (separation, distortion) are nothing special. Gangs & Filters The TX-7500 and TX-8500II have many similar parts. Some say that the TX-8500II is almost as good a tuner as the TX-9500II. Easy to get in, but they want to throw the whole tuning off-center, and I think I know why. Pioneer F-99X (1985, $325, front1, front2, back, schematic, Audio review) search eBay But more than any one thing, excellent sensitivity stands together with excellent rejection characteristics. Our contributor Lorne tells us that the TX-8800II, in addition to the extra gang, has wide and narrow IF bandwidth settings, a larger chassis and a bigger circuit board. The AM and FM sections have rich audio. There are 3 IF 3-pin filters, two of which are blue MX GDT type. The wide/narrow switch and filter configuration distinguish it from its virtually identical predecessor, the TX-9500. With a Pioneer NEX in-dash receiver, sound quality features like built-in Auto EQ and Time Alignment, 13-Band Graphic Equalizer with touch panel swipe settings and built-in high/low pass crossover with adjustable points and slopes provide you with the controls to tailor the listening experience to your vehicle and listening preferences. I also upped the power supply and bypass caps. The large TX-1000 dial scale was specially designed to be read at a glance. The sockets will eventually hold a pair of Bill Ammons's amplified filter boards. Home Other features include fixed and variable output level controls, multipath output terminals and an MPX noise filter." See how our panelist Jim thought one F-90 sounded compared to other top tuners on our Shootouts page. Whether you’re deploying an entirely new wireless network or migrating from older equipment, this guide contains all the expert knowledge you’ll need to succeed. The tuner uses a 2SK241 RF amp, HA11225 IF amp/detector, AN7470 stereo decoder, LA1247 AM chip, LC7217 PLL, and M5223 varactor driver op-amp. Additional information on the TX-9800 is available at classic-audio.com. The TX-7800 has only one IF setting for FM so it's not likely to satisfy the competing desires of an audiophile-DXer as well as a KT-7500 (for example) might, because a filter mod to maximize selectivity in the TX-7800 will necessarily affect its audio quality. Since Bill Ammons observes that the TX-7500 is very similar to the TX-8500II, that certainly must be the case for the TX-7500II as well. When I tested them for adjacent-channel performance, the TX-9800 and KT-8300 could both ignore the adjacent, but the ST-7405 had lots of interfering hash." High-End collectors!
