Pioneer - SX-450 Stereo Receiver Audio amplifier

Very nice, from the original owner, Pioneer SX-450 stereo receiver, in handsome condition, tested and in working order.
Description
The Pioneer SX-450 is a 15-watt FM/MW stereo receiver with FM muting, tape-monitor switch, and 2 pairs of speaker connections.

The unit uses a directly coupled OCL circuit in the output stage with a differential amplifier in the first stage.

A high FM sensitivity is guaranteed by a low-noise FET in the preamp with a frequency-linear 3-gang variable capacitor.
