    Not wanting to thread jack but here's a thought that I haven't explored completely; I wonder if this would work given that the B-3 is so very similar by design? If you're confident that only the V-FET's are dead on the one side and the rest of the circuitry is fine, you could remove the dead ones and then transplant one pair of V-FET's from the working side to the non working side and you'd have a B-1.75 ... :)

    The Chinese seller from which I have bought the B-3 says he own another B-3, but without the original V-FETS. He modified the amp so now is based on some RCA transistors (IRF...).Are these good replacements?
    Of course, the price is lowered with like 20% comparing with the one I bought. I told him that I am not interested for the moment, because I do not know for sure what other modifications he operated to this unit. What do you think?

    Not everyone has a pocket full of V-FET's. ;) :)

    Why bother?

    Edit: Scratch that,
    The B-2 is worth repairing. My "why bother" comment was for the modified B-3.
