The TU-280 FM/AM tuner implements a varactor, 3-gang equivalent front end feeding an IF strip with 2 ceramic filters and a single IF bandwidth. The IF strip is initiated with a 2SK161 MOSFET, and a 2SC2839 bipolar intermediate gain stage, fed directly into a Sanyo LA1851N DTS single-chip tuner IC. The tuner IC supplies everything between the IF and audio stages. The audio stage itself is formed in discrete components, with no buffer and a discretely formed low-pass filter. The front panel houses a digital station frequency readout, mono/stereo lights, but no signal-strength meter. There are 30 station presets and a remote sensor, paddle tuning, Power, Auto/Manual, Memory and Band rounds out the controls.
