A vintage Pioneer SX-450 receiver that had a loud hum on the output.

This is a receiver from the days of wooden end cheeks and brushed aluminum front panels, something manufacturers don’t do any longer.

The fault was due to a failed capacitor in one of the power supplies putting mains hum into the preamp.

If you have a faulty Pioneer SX-450 or any other amplifier or receiver you need repairing please contact me for a quote. Items can be dropped off or shipped to me.

In the world of power amplifiers it’s nothing special at only 15W per channel, but it’s well made and looks far better than a lot of modern HiFi.

It doesn’t sound too bad either from its proper transistor output stage.
