This is the Pioneer SX-780. It was the last of Pioneer’s 700 series receivers and was very well built. It was produced from 1978 up until 1980 and had a list price of $325.00.
The SX-780 was rated at 45 watts per channel but that was probably under rated. The internals were high quality with Darlington STK-0050 Power Packs in the output stage as well as high quality Nichicon capacitors.
While it had crisp FM reception some feel that its FM selectivity is a little weak. It also has a great phono pre-amp section but could have used some more AUX inputs. Overall a great starter receiver for someone just getting into the vintage audio scene.
