I replaced the filter caps on a B115 I picked up recently. Everything was fine, it sounded good, but there was some buzzing. The buzz seemed to be coming from the interlock switch. I replaced that and when I turned it back on, with all volume pots at zero, My speaker crackled and smoked. Its completely fried. Did I connect the interlock switch wrong? The switch itself functions. Is the power transformer bad? Any help would be appreciated. This is a mid 70s B115 SS bass amp.
