Amplifier (Bush) query

Wrong forums I know, but someone may have a clue.

My admittedly cheap Bush Hi Fi Sytem consists of 3 components, but the
Amp I notice no longer
generates output on Left channel.
Digital Tuner/CD player fine.

I've checked wiring of speakers and reversed connections between left
& right, and it confirms
fault is in amplifier output.
Taking apart hoped may have been blown fuse on the pcb but none of
those inside at all.
Will check for dry joints in relevant area ie channel outputs.

Any other suggestions afore I bin as to which component failure likely
to be in appreciated;
otherwise off to Richer Sounds!.
Thanks.

Perhaps you might find something here.

You will at least need a DMM and be able to take some readings with the
item powered on. Being stereo gives you two identical halves of the amp
to make comparative measurements.

What's the model number. Maybe (but no promises) a schematic might be
out there.

But given the price of these things, maybe a replacement might be for
you. If your tastes in music are purely for background entertainment
walking into a hifi shop is unnecessary, and cheap integrated compact
systems won't be found there. I'd try John Lewis or Currys over Richer
Sounds in that senario.

Just attach both speakers to the working channel. Next time try a
decent second hand item instea of new junk.

I recently bought a second-hand Arcam Alpha 6 amplifier off e-bay for
£40. It's sensational. Equivalent new at least £250.

I take it this is one of those items that looks like separates but is all
powered from one basic unit in the case.

Two things to look for. Sometimes these items use modules for the sound
output. They tend to be screwed to the biggest bit of metal inside. Its
highly likely that one of these has failed, and if its not too old one can
fix them by replacement.
There was one maker of these badged systems who pushed the boat out big
time and put two identical voltage regulated supplies in, one for each amp,
but fed from the same transformer of course. Its possible one has failed.

Mind you unfortunate thhough it may be, most of these, if they need someone
whos time costs money to fix are uneconomic to get sorted. Its cheaper to
just get another Chinese built box instead.


You might hhave problems if it contains a tape machine of two though.

Come on, in actual fact these cheap items can sound nnot bad. The weak link
is normally the speakers I find. Of course they are not going to shake the
walls on organ bass notes but they can sound reasonable. Also think more of
them really should spend five pence on an aerial socket as well instead of a
bit of wire.

Gives fm a bad name!

Don't top-post, it makes the baby Jesus cry, especially at this time of
year.




No.

Does Top posting make sense?

Brian is blind, it is it is admirable that he posts here at all.
