    I have the same problem with mine, I opened it up and found a burnt fuse (the 2.5 amp one) and replaced it. When I turned it on the power transformer hummed loudly like it was under a big load then the fuse flashed and burnt out again. My father thinks it a problem in the transformer it self but I have no way of testing this. If your unit was really warm on the top left side this will confirm you are having the same problem.

Mine had the same problem... turned out one of the big transistors (the ones attached to the heatsink) was dead, got a new one (not the same one but with the same characteristics) and voila! though i didn't actually do it, i left it to a technician xD Good Luck! MicroSeries FTW

Does a technics stereo amp su-g90 have a stereo to play music


This device does not have an internal tuner. It is simply an amplifier. The buttons on the front labeled TUNER - TAPE - PHONO - DAT/VCR 1 - VCR 2/TV are selector buttons for additional components that hook up to the respective connectors at the rear of the unit. If you want to play a radio with this device, you must buy a tuner and attach it to the tuner inputs in the rear of the unit.

I have a technics su-g75 amplifier, this system hasn't been hooked up for a few years but seems to be in excellent condition. It plays and seems to work great. I don't know whether this is a problem or...


Yes the unit will get fairly hot. If you can keep turning it up at some point the fan should kick in, if it doesn't then it need looking into further.

Technics SU-G95 Amplifier and no sound on left speakers


Usually this is a defect in the output amp IC. If you have no experience with repairs of these types of units, have it checked by a service shop. If the output AMP IChas failed, it will cost about $75 for a replacement. This unit uses an RSN3306P IC .
