I have completed the hardware assembly, but I'm thinking of painting the transformers before I start soldering. I will make a decision tomorrow. I'm very interested in how the amp will sound with the theatre 4's. I think it will make wounderful music. I have a Tosh SD-4960 that I have not mod yet. Waiting on some parts, but if I get a chance to work on it before I can get over I will. I will let you know how the build is going and thanks for the offer to help.
