Hello fellow enthusiasts.
A friend of mine gave me one of these Technics SE-9600 amps, asking me to check it out.
It hasn't been fired up for some time, so I started with mixed feelings.
Here's what I found: After I turned it on, it worked OK for some minutes. Then the volume decreased and distortion increased.
I turned it off and waited a minute. After turning it on again, the same happened, but a lot quicker than the first time.
Maybe its just the dissipation paste that needs to be replaced, Maybe its something more serious.
Any suggestions?
Thanx in advance,
Phantombox

I forgot to mention: the huge heat sinks stayed cool all the time. (Maybe it not the dissipation paste after all)

On an amp this old, electrolytic capacitors most likely need renewal. It could be a coupling cap going bad.
Technics, SE-9600 has the service manual. Looks like it has some kind of regulated power supply.
