Pioneer F-28

The other tuner in the Series 20 line was the F-28. It differed in appearance and price (lower) from the F-26, but was still a superb performer. It employed Pioneer's Photo Logic Synthesizer/Quartz Locked system and "Clean Pilot" circuitry. It also used the Parallel Balanced Linear Detector and featured selectable Wide/Narrow IF Bandwidth. The circuitry used a 5-gang variable capacitor for higher tuning accuracy to improve image response, spurious response and IF response ratios, all having 120 dB or better.
Its signal to noise ratio in mono was 84 dB and in stereo 81 dB.

The F-28 employed 10 FETs, 21 ICs, 63 transistors and 56 Diodes. It measured 16.56 inches wide, 6.12 inches high and 14.21 inches deep. It weighed 19 pounds, 13 ounces and had an M.S. R. P. of  $690.00.
