Question about Audio Players & Recorders
I have an SU-G70 Technics Ampilfier. It stared out by working for hours, maybe all day, then it would just shut down, completely off. Now it's to the point it will only work for a few minutes before it turns itself off. I could get it fixed locally if I could get a schematic sheet on it. Or, if anyone has a suggestion I'm open for it.
a 6ya expert can help you resolve that issue over the phone in a minute or two.

I just got mine back from repair shop, same symtoms, they replaced power supply, in your case it was hit and miss for a while, so maybe bad power supply connections inside.

SOURCE: over heating
make sure there is nothing within several inches of it to start off. if need be, use a small house fan pointed at the amp to help cool it, if all else fails and/or you don't want to hear the noise from the big fan; get a computer fan the same size as the one in the case. connect it in place of the fan that does not work(may have to cut/splice the wires). that should work. oh, check the voltage and whether the fan is AC or DC from the stereo. this makes a huge difference!!!! if the fan says "DC" DO NOT CONNECT AN AC FAN TO IT!!! the fan will short and BLOW UP!!!
