Sansui 771on the bench to change a few components

this is a nice receiver , ok to work on and a service manual come in very handy. change the C1313 transistors and capacitors as customer request...I will show you how to check the bias if yours need to be checked. But at the end of my video, I did notice I had some kind of interference that is always present after relay clicks in, a low noise almost sounds like a ground issue. I will not be covering this humming on this video, unfortunately, I had to move on to the next amplifier as promised but I will get back for this issue...that I promise. Enjoy and subscribe to Joe'sBench506 any ideas on how to find this low key noise in welcomed also.... let's start a conversation!!! Maybe we can find the issue together!
