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.
