Hi guys,
I have a Sound X404 here that seems to be working great other than a sometimes failing 2 prong power plug. Usually I say if it aint broke don't fix it but the person would like the caps replaced, tubes changed, and a grounded plug added so here go's. I think it's a pretty rare and underrated piece. It seems to handle both bass and guitar very well while coming across as clean and thick. It only breaks up a hair at loud volumes with a strat with regular american pick ups.
I don't see a schematic anywhere online, or recognize the power tube type. Unfortunately there is no label on the power tubes other than RCA. Does anyone recognize these or have a schemo for this amp?
