Technics SU-C04 Amplifier. Left on for about two days, then radio played pushing power, Kinda loud. Amplifier just quit, then noticed it was HOT. With power to amp, pushing the on / off switch to on, no power. Does not respond. I would like to have this repaired if possible and if reasonable. Please advise. Thanks

    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

The amplifier power transistors could be bad, the speakers can be muted or a fuse for the speakers could have opened.

I need a volume control knob for a Technics SU-X101 Sterio Amplifier


You can easily salvage one from a scrapped or damaged set and this will not be hard.
So please visit the nearest audio/video service centers and you will be able to get one easily from a set that would suit the technics amplifier.

I have a technics amplifier SU G75


I have a technics too, and faced the same problem. The solution is very simple just ensure the +ve and -ve wires are connected correctly for each speaker to the amp. Eg. red wire to the red knob and black wire to the black on both ends. sometimes this arises because the wires are of just one color however there will be some marking on the wire to indicate which is +ve and -ve. This took care of the overload problem.

Technics SU-G90 Amplifier from the late 80's. Unit will click off after a few minutes on. If left alone, unit sometimes clicks back on, with a loud "pop" from the speakers. Tapping the unit...


because bad connections, probably in the driver section of the endstage, dc current apears on the output and shuts down the output through the relay.
