I've been given an Eden Nemesis NC250 bass combo, partly because the owner wanted rid of it and partly because they feel it is currently un-sellable due to a buzz, which I've now had a listen to and will need to get fixed if I'm going to be able to do anything with it.
The buzz is there as soon as you switch on and appears unaffected by any of the controls - even with the gain and master turned up full it still makes the same noise as when they're both all the way off. Every control does something when a bass is plugged in (though the compressor seems a little weak (and its LED doesn't work) and again the buzz is there in the background but doesn't change whatever is adjusted
I ran a patch lead across the send - return of the FX loop and plugged in some headphones - no change.
As I know nothing about repairing amplifiers I'm going to have to get someone who does to look at it, what I need to know now is probably a question that's impossible to answer - will it cost a little or a lot to track down the fault ?

Don't count on it though.

I need 8200µF / 80V and the ones in there (Su 'scon) don't appear to be too popular, any recommended brands/suppliers ?

I discovered the other day that the caps have been glued (or at least, that's what it looks like) to the board, but I'll update as and when I get them replaced.
or would replacing every capacitor be worth a try ? or re-flowing all the solder joints?
I'd rather save money and fix it myself but if I'd be better off handing it over and maybe paying £50 then I could live with that, my only fear is that making it noise-free will cost me as much as it's worth (or worse).
He's going to sit it on a pad in the hope of reducing some of the noise (No new transformers to be had according to Marshall, who are the distributors) and I'll see what the result is before deciding what to do next.
It does mean that it could be gigged without a problem, but it may be useless for home use.
