I have had this lovely AV Amp for a few years now




Unfortunately it's just stopped working. It appears to be working but no sound comes out.

Is this likely to be an easy fix or is it a write off?

My local repairer wants £50 just to look at it and tell me if it is repairable

there are some basic checks that you can conduct, and if you have an oscilloscope there is even more that is possible.

Simple checks include looking for DC power in all the right places,... follow the DC power rail round and see where it goes. Check for fuses, and capacitors that don't look right.

If you have an oscilloscope, then feed in some music and follow that round as see where it vanishes. In all cases take sensible precautions around the mains elements.

Oh and a simple check on the switches and stuff too. An hour or two looking in the box may well save it.

worth a look I think

Im no expert, but I would certainly whip the cover off and check the internal fuses. Had a cambridge audio amp that was fixed this way, and a Kef sub that I aquired 'for spares/repair' with blown backplate fuse.

As said, also capaciters that look sweld or covered in crusty goo, and any burnt/damaged components/tracks on the boards.

ok it's open

I've found a total of 5 (well hidden) fuses which all look ok

I found this cap which looks a bit grubby - could this be it?

not sure but this seems to be on the video card bit so it doesn't seem likely

I would start over on the LHS by the transformer and check where the DC is going,...
