    I was gonna say..
    Yes that is the way to go. That is what I did with my unit for the Quickie, albeit, I would not call it a full rebuild.
    The next B-1 I will do 'll be my Hot-Rod B-1 with silver front plate. That will be a full rebuild. I plan on eliminating all but two of the relays, by pass all input switches and the rumble filter, new speaker posts, a proper power cord for 1kVA and I even found a good cleaning "solution" for all board edge-connectors :D

    I came across this site for the board connectors. But will try to clean the original first.

    Yes I know :) Let me know if you also want a high-res digital copy of the B-2 flyer (German unfortunately) or the NS-2000 flyer (English).

    Hi Pete,

    What did you use for the 2SA-810 and 2SC1452 on the driver board?

    I can see you replaced them.

    KSC3503D/KSA1381E (no longer available with same rank)
    or
    KSC2690AY/KSA1220AY

    either would work
    The first pair no longer available with same rank
    Second pair a bit higher Cob than the originals
    Either would be work and be more reliable that the original


    These are TO-126 devices so watch the heigth. Also know that I have a patent on those heatsinks. Can't use the same kind without special permissinon :)
    your only choice is to go with a la Amp8 version:D:D
