Kenwood 8340-AM
The Kenwood 8340-AM has almost no documentation outside Kenwood's own advertising. The period record, specifically ads from late 1973, identifies it as the KR-8340 AM/FM receiver. The ads pitch it as a single unit that promised strong two-channel performance and also delivered four-channel capability (High Fidelity, November 1973, p.160; the same ad copy appeared in HiFi/Stereo Review, November 1973, p.83).
The hook was a four-channel receiver whose four separate amplifiers could be switched for two-channel use, combining their output into the front channels. You got 25 watts RMS per channel with all four channels driven, and 60 watts RMS per channel in 2-CH stereo mode (High Fidelity, November 1973, p.160). In four-channel mode it supported RM, SQ, and CD-4 - the last one needing an optional decoder/demodulator (High Fidelity, November 1973, p.160).
Past those advertisements, nothing else is documented. The Archive's sources have turned up no independent review, no confirmed original price, no production run and no circuit details.
