TECHNICS "OVERLOAD"

[L1ange bleu]

TECHNICS Model SA-AX610 Amplifier. When turned on, it reads: "OVERLOAD". TURN
SET OFF. The relays try to click but inmediately they shut off...I've checked
the electrolytics in the power output for any AC on them but couldn't find
much. Any advice will be much appreciated.
TIA

This amp probably has shorted output devices, such as output transistors,
and their respective drivers, or the main output IC, depending on its
design. Once the defective parts are determined and replaced, the cause of
the failure should also be serviced before re-applying the power back on.

I believe you need to determine which output IC is bad.
Technics models often suffer bad solder connections at the voltage
regulators and output IC's - this could be your problem as well.
