Rare TEAC TX-500 High Performance AM / FM STEREO TUNER + ORIGINAL MANUAL MADE IN JAPAN Looks great and works great as fully tested. A photocopy of the Service Manual is also included.Highly rated tuner that sold for $350 in 1979:Our panelist Ray found this extremely rare analog tuner hiding beneath a rock and took it home for $18.50 + $28.85 shipping -- sparrow feed for sure. Technical highlights: 4 FM gangs and 2 AM gangs. Dual IF paths, each with its own discrete buffer from the mixer. Wide has two 250 kHz GDT ceramic filters and narrow 3 250 kHz GDTs. The tuner has the better ICs of the time with the HA11225 IF/quad detector feeding the HA11223 MPX. Twixt them is an interesting 200 kHz notch/LP filter and discrete buffer. Audio stages from the MPX consist of discrete buffers (lots of those in this tuner) to pilot notch filters to a 4559 output IC. Some claimed specs: IHF sensitivity 13 dBf; 50 dB quieting 41 dBf in stereo; S/N 65 dB; THD 0.12%; and separation 50 dB, all in stereo. Measured frequency response was -1.4 dB at 20 Hz and then -0.20 dB to +0.35 dB, 40 to 15 kHz. De-emphasis time constant was 70.5 µS. Subjectively RFM found the TX-500 to be pretty hot (sensitive), giving his TX-9800 a good run and the sound, stock, was typical of the late 1970s -- pretty good. It was also easy to mod.
