Disassembled an ST-70 that spent most of it's working life inside a smokey bar. The original cloth covered leads are extremely fragile and the colour coding is mostly gone. Taking the end bell off I was able to figure out almost everything. I have four leads left that I think are the three centre taps and the bias supply. I have photos of the xformer that I could send (or post if that's possible). Can anyone help? Thanks, Paul
