Pioneer SMQ-305
An AM/FM stereo receiver from 1973 with tube-based amplification and 14 watts per channel output.
Overview
The Pioneer SMQ-305 is an AM/FM stereo receiver introduced in 1973. It puts out 14 watts RMS per channel into 8Ω loads. It tunes FM and MW (medium wave). The audio circuitry uses vacuum tubes: 12AX7s in the preamp and a pair of 6BQ5s in a push-pull output stage. The phono input takes MM (moving magnet) cartridges at a sensitivity of 3mV. Speaker loads between 8Ω and 16Ω are fine.
