Question about Audio Players & Recorders
I have this reciever that I bought back about 1980. It quit working several years ago and got put on a shelf when I bought a new system.
I thought the switch had gone bad, but when I got it out recently and tried to fix it, I found that the switch was ok, that there was some other problem. When I turn it on, nothing happens, no light on the dial, no static on the radio, nothing. I took the cover off and tried replacing the fuses that I found there (3) but still no luck. I couldn't see anything that was obviously out of place, no loose wires or anything.
Thank you for your help.
There may be some missing voltages from the power supply or a circuit pulling it down. Needs to go to a shop that knows how to fix older equipment.

I suggest you get a schematic, find the main power transformer -- not the big one -- and see what the output voltage of it is. Could be there was a line surge and it cooked a zener diode that regulates power supply voltage. I can help you find a schematic.
