Pioneer SX-780

Pioneer SX-780

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.

  1. I have one of these that powers on but doesn’t deliver sound through the speaker outputs or the headphones. Is there a common cause for this that you are aware of?

  2. CAN I USE THE STEREO/MONO SWITCH FOR LISTENING TO STEREO/MONAURAL, AND FULL FREQUENCY RANGE RECORDING REGARDING VINYL RECORDINGS? IF I’M NOT LISTENING TO A STEREO RECORD, SHOULD I SWITCH TO MONO? THANK YOU FOR YOR HELP.

  3. Yes, I would engage the Mono switch. Mono will mix the right and left channels and should lessen the noise from a monophonic record. For a couple good reads regarding mono try these links…

    Both cover the basic ideas behind playing mono recordings.
    Good luck!
