Cheap-ish, maybe, depending on how off-the-shelf the replacement parts are. Easy... probably not. Depends on how skilled you are in electronics repair.

FWIW, the service manual is here: http://www.audio-circuit.dk/Schemati...001-int-sm.pdf

cheap and easy no - chances are one or more output devices have blown.

Yes, but the outputs are only $2 - $3 a piece from B&D, and there are only one of each polarity per channel. So, parts-wise, it could be cheap, depending on how much additional damage their is.

Easy is entirely based on skill. If it's just blown outputs, it would pretty easy for me. For others...?
