Hi y’all. I have a pair of TAD-1000 monoblocks made by the late great Paul Grzbeck. I also have his TAD-150 Signature preamp. I am interested in any information that might be available for either of them: manuals, schematics, etc., but what I REALLY need right now is biasing instructions for the monoblocks. I should say that I have the later model that has lights on the bias pots. Does anyone have this info? Thanks in advance.
Patrick
