[QUOTE="thch, post: 5757360, member: 562032"] not sure what you're calling 1/2/3/4. clearly two windings will be thicker and two will be thinner. from there, i'd hope you know the way you re-wound the transformer, and have some idea of how to reconnect it. It might help to use a DMM to see which pads connect to things like +12V, or each other. I'm guessing two connect to 12V and the other two connect to tabs on the transistors on the bottom. use the black lead for the transistor tabs. I'm guessing there's a part i'm not seeing. in anycase, the other pads probably connect to the large dual-pack diode in the upper left corner, as well as whatever point can be used for "ground". possibly connected to the RCA cabled via some resistor, or maybe one of the speaker terminals. all of that assumes a single output push-pull. the lack of dots on the transformer diagram might indicate there is a 50/50 chance this will end badly. the coloring of the wires seems a bit off as well. Have you also changed the windings on the transformer? [/QUOTE]
