Default technics SU-CH9 mini-system amplifier

This is a Bi-Amp from a Technics mini-system from about 1990/91. After 15 minutes of use, at moderate volume levels the bass side amplifier cuts out on both channels with a loud click (heard on the speakers). Power off, wait a few seconds, power on fixes it. No visible signs of fault - dust etc. Any clues, or suggestions for repair (London UK).cheers,Greg Allen


Greg, you have a state of the art piece of equipment. It seems that maybe something related to temperature is bodering after a few minutes. review this and change the ventilation device is cheap and easy. I have one at home and one day decided to connect it to a pair of B&W DM603 that allows bywiring and the result I got is incredible. The quality of sound is hard to believe and has nothng to do compared to the original speakers. I also tried the same speakers with things like YAMAHA M65 (power amp 170 W per channel), YAMAHA RVX 795, Luxman 1000 series and none of them are close to the sound of hte Panasonic / Technics.Also I have apair of MS speakers and tried with again excelent results. Good luck with your SC.

How can it be state of the art? The message is from 1998, and he says the
system is from 1990/91.

Read the date on the messages before you post. "Greg" isn't here anymore,
and chances are good he wasn't here much longer than that post. Hardly
anyone sticks around.
