DR #44 - Pioneer SX 1980 Classic Audio Receiver Restoration - Chapter 2

In this video, I continue my restoration of the Pioneer SX-1980. I replace the bulk electrolytic capacitors, install an upgraded power supply board, power up the receiver, troubleshoot and re-work both amplifier boards, and perform some initial testing. A lot of work done, a lot more to go.
