Hello.
Integrated amplifier HARMAN KARDON PM 635.
Strange problem.
Power on.The amplifier sounds clear, no problem. But after 1-2 minutes, the sound slowly disappears on both channels. After turning off for 10 minutes, the sound reappears for a few seconds and then slowly disappears again.
No bad soldering.

Thank you.
What Mark was trying to point out was the logical engineering way to locate a fault like yours ,even TV engineers use spray or a heat gun to aim heat at different parts of a circuit to bring on the fault quicker.
Coolant spray can sometimes restore a faulty circuit long enough to locate the area of a fault but you seem pretty adamant that nowhere on your amplifier is faulty --yet you complain it cuts out and that I take it is with the power supply in good working order --yes ?
Clip on your meter to the plus and negative supply lines AT the OUTPUT --run your amplifier and watch your meter .
Try and remember we are working virtually not sitting at a workbench with a host of test equipment connected to your amplifier .

So you really did resolder every joint? You did not? Than this is an assumption only
