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. -- Greetings, Jerry Greenberg GLG Technologies GLG ========================================= WebPage http://www.zoom-one.com Electronics http://www.zoom-one.com/electron.htm ========================================= "L1ange bleu" wrote in message ...

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. Mark Z. -- Please reply only to Group. I regret this is necessary.
