    Is there a tape monitor switch that's ON and not supposed to be....or a Mute switch that's ON?

    Do the headphones have the same problem?

Problem with older equipment is that mechanical switches corrode. Try some tuner cleaner on switches. One side cutting out may require the speaker leads (inside the cone of speaker) to be re tinned. Old speakers and lossa mileage cause solder to break up into powder. Re tinning the flexible link (looks much like a wick) allows that electricity to get into the speaker coil. If all else fails those old TV repair shops actually do have real techs that can fix it. Not like the current Geek Squad type of replace replace reboot replace type of tech. Good luck. Ed

Power down,disconnect the speakers and power back up. If it still say's overload, it needs to go to service. If not, check your wires, connections, and speakers one by one to hunt down the problem and correct. Hope this helps

Good day i have a Technics amplifier SU-X320. Problem is it powers up up there is no sound. Checked all basic fault finding, suspect it is the volume IC.


"Volume IC" do you mean an IC that is a pre-amp and controls the volume and things like tone? Or do you mean the main power amp IC, which will be on the big heat sink?
If you amp uses the latter and not individual separate devices for the power amp, suspect that over the other IC. But if the amp has separate power amps for both channels, replace the IC.

My technics amp SU-G75 keeps shutting off and reads OVERLOAD when played over the volume of -40 to -35. I kept playing around and it works fine when the bass dial is on half, but more bass shuts it off. I...


some amps are made more for low ohm loads (bass) and some are made for high impedence loads (mids/highs) and it seems you are asking too much from your amp.

Technics SU-V98 No Sound


If I understand your posting correctly, the amp works using the Aux In connectors but not using the VCR1 even when VCR1 is selected correct? If that is the case, there is an internal electronic switching IC (TA9263 I think) that may be defective. This is not a complex repair and can be confirmed easily by any shop that does audio repair. They will trace the incoming signal with an oscilloscope to the IC and see nothing come out when VCR1 is selected. The IC costs less than $10.
