I have a 3 channel Bryston power amp which is currently blowing one of the internal fuses upon powering on and I am trying to decide what to do with the amp regarding the fault, specifically do I get it repaired or sell it as is in the faulty state. The other two channels are working fine and it sounds great as a 2 channel power amp but I was hoping to use this for the left/centre/right front speakers in a 5.1 system. I have contacted PMC about the amp who have confirmed they would be prepared to undertake a repair, and they have quoted a perfectly reasonable cost of £70 for an hour of diagnosis which would then be deducted from the total repair cost if the repair is undertaken. My amp is well out of the 20 year warranty so a paid for repair is to be expected - I am not wanting a freebie - but it would be handy to get a rough idea if at all possible, of what the likely problem is and what their potential charge could be. I also want to know how long a piece of string is .
I've attached a few photos below where you will hopefully be able to see the charred/scorched area between the fuse holders for channels 1 and 2, as well as some general photos showing the internals. There is nothing visibly apparent on the boards other than the scorched area between the fuse holders, though I am aware that problems aren't usually visible. I don't have any history of the amp so no clue as to what happened to cause the scorching near the fuses, but I do know that the insides were under a carpet of fluff (see last photo of it pre-cleaning using a soft brush and hoover). Does anyone have any ideas of repair costs at PMC for Bryston stuff, or any guesses as to what could have caused the scorching and subsequent blowing of the fast blow fuses?
