If the receiver works at low volume, but goes into OVERLOAD and shuts down at higher volume, it means you are player the unit too long and too loud. Try yo keep the volume down to a reasonable volume.

If you have the skills, these technics amps are known to get bad solder connections on the amplifier ic's and voltage regulators. You can access these points through the bottom access panel. Look for any fish-eye solder joints.

Overloads are often caused by short circuit conditions on speakers or the wires to them. Remove all speaker wiring and then try powering up. If the overload light continues to come on you might have blown something on the main amp board, such as a power transitor, that was caused by bad wiring or speaker problems.

    That can be true, especially if the wrong speakers are fitted making the amp work harder. However a fault can also cause it to do that too.

    Just some more input, if you had a speaker wire shorted, or a bad transistor(unless it's an overload transistor)it would not say OVERLOADED, it would say PROTECTION, as in a blown amplifier.

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

SOURCE: I have a Technics Stereo Integrated Amplifier

Are these resistors near or linked to whatever is on the heat sink? If they are then they are bais resistors and they have burned up due to a fault on the devices on the heat sink.
Resistors are cheap, all you need to do is find out what value they are. This is part of the colour code. However if they are burned then you might not be able to read the code! So you will need the circuit diagram or someone to tell you the value.
The problem however will be if whatever on the heatsink has gone!
It could be an IC since you have lost both channels, unless you have shorted the speaker wires of both channels somehow and blown both right and left amps!

Technics stereo SU-G75 power comes on For 5 seconds then overload light appears


Hi try to unplugged your speakers directly to the ampli to test if you don't have a short circuit with the lines or the speakers. If the problem persist you have to go to a repair/shop.
Have a nice day

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

I have a Technics stereo integrated amplifier SU G75. The cooling fan began making chirping noises then stopped. Now every time I turn the stereo on I get a overload message. Could it be the cooling fan...


It chirped because the bearings were worn out, then it froze up and isn't moving any air. Get it replaced. DO NOT run the unit if it keeps overloading or you will have a bigger problem.
