Telefunken Studio 1M

Telefunken.... one of my prize possessions. Recently noticed that the sound gets faint and scratchy after a few minutes, as if some contacts were getting old, dry and dirty. During my trial and error of what knob it could be, I couldn't diagnose which it was until I hit the power button. The sound becomes full again for a few moments after I turn the unit on and off. The power button is a spring action up and down. The sound stays true when I keep my finger on the button holding it all the way in. I automatically what to deoxit the power contact.... I just want to make sure that everyone agrees before I try to take off the face of this beautiful box. If, so.... has anyone taken the face off of one of these before? I would love some advice. Thanks Boomboxery

I don't have this model but there are members here who can advice you with the opening of the unit.
Prize possession needs maintenance.

Also think deck door needs to be open.
I would replace the main amp capacitors while you're at it, these things are very old.

In my case, one of the fuse was burnt and on that channel i heard similar sound like in your description.
