So another late night bench session. It’s 1am and I’m off to bed. Two and a half hours tonight on power supply board and caps for a Pioneer SX-636 receiver. Replaced all electrolytics with Nichicon PW series and Fairchild transistors. Large power caps switched to Nichicon KW series and mounted under chassis as they are a third of the size. One chemi-con power cap was leaking oil all over. Receiver presented with right channel out with loud hum and popping. Receiver is getting complete overhaul and should sound awesome when completed. Going to make someone very happy in its new home. Here’s the finished power supply board, good night.
