    I need a preamp board for my 400RB-4 head. The factory tells
    me they don't have one and won't have any more since it is a
    discontinued model. Gallien Krueger.
    Anybody got an idea where I my look for one?

    Is yours beyond repair?

    It is beyond any help according to my repair guy. He's good.

    Unless the PC Board is broken or burnt they are simple to repair? I'm surprised G-K no longer has replacements, they have not been out of production that long? I have service info for the cost of an email addy if it will help him.
