Just pulled this out of a suitcase, I put it in there around 40 years ago. I forgot I still had it. Looks like it is in great shape, over the weekend i`m going to pull the cover and blow it out good and maybe deoxit what I can.
Got the unit blew out and sprayed deoxit on the pots and sliders.
I hooked up a set of speakers and a IPOD to the aux, powered it up and I have a "hum" coming thru the speakers. It does not matter which source is selected, the "hum" does not change.
Does anyone have any ideas on where to start looking for the problem? I have the schematic and a dmm.
