Define 'dodgy left channel'?


Well it started to get a bit wooley on the left channel. I bit muffled
and quiet. This was most pronounced when switched on and, for a while
(read a few months) it would clear up after it was warmed up. However
it got gradually worse and then went completely. Then I moved house
and it stayed (along with the rest of my HiFi) boxed in the loft. That
was 5 years ago! Anyway we're just about to move to a new house which
has an extra room which is going to be my HiFi room so it's time to
get it out!


It may not be a fault as such, or it maybe something that someone with
a soldering iron can fix in minutes.


It's getting the time to look at it which I just don't have. I suppose
I could just resolder every joint :-) There can't be more than 20 per
channel.

TBH it all looks pretty standard parts except for one module which
looks like a custom job.

Hmmm.... just taken the lid off to remind myself..... Getting the PCB
out looks like a ba**ard - great big row of D896 power transistors
fixed to a large heat sink which is then attached to the rear of the
case :-(


Other than that, Richer Sounds have a very good repair department, and
they'll lend you an amp whilst it is away.


Richer Sounds.... now there's one in town - might give them a bell.
