SS Receiver Putting

[JohnA]

What is the most likely cause for my '70s SS receiver popping/putting with the volume at zero and no input?  It started this over the weekend.  It was recapped 4 or 5 years ago.

 .failing , aging semiconductors  +  related parts  ,  defective , worn out  , switches   relays  ,   potentiometers  ,

Sounds like something else went bad. Probably a resistor, transistor, or a bad solder joint. 

[JohnA]

A lot of stuff in these old receivers is no longer available, the output chips in particular.

Clean the pots and switches is ALWAYS the starting point.

in alot of 70's-80's sansui there as 2SA726/725 Transistors that make odd pops and hissing as they age. I have a list of 20 remove on sight Transistors because of break down issues and noises. this also goes for most vintage audio from that era. clean the switches and Potentiometers first, you have ruled out capacitors.
