In Reply to: Hum appears out of nowhere on vintage integrated amp (all functions): is it toast/repairable ($...)? posted by ParloFax on November 16, 2023 at 07:37:09:
If you want Vintage equipment to operate as new, be prepared to extensively service the unit early in your ownership of the unit.
There are lots of possibilities for this to occur-
Cold solder joint
Cap aging
resistor/transistor aging (leaves open circuit when warm)
etc.
Happy Listening
