It just developed a 120hz "square wave raspy" buzzing in all channels. FM is very staticy with weak reception in the background. Buzzing gets louder as the volume is rotated higher. Inputs have audio with the buzz in the background. I suspect the power supply.
Everything seems to operate ok. Protection relays are clicking like they should and it powers on ok with all functions working. I pulled the plug on it for the time being
Does anyone have a schematic and voltages for this receiver? It's a virgin unit that I've owned since it was new (waited almost 2 months to get it). The cover has never been off. I know a recap is in order. Any suggestions would be greatly appreciated.
I have a sparse but adequate bench of equipment. Signal gen., 'scope, DMM.
Salutations beforehand, all!
