Has anyone out in webland got a schematic for the little front end daughterboards used in the 7.250 to convert from balanced (XLR) to unbalanced. I know this SHOULD be dead simple bot the boards contain a bunch of other semis whose function I cannot determine. Amp came in with a deceased THAT1250 which is a very rare beast indeed and theoretically interchangeable with a SSM2141 (which I stock). Regrettably the theoretical did not match the practical and the SSM did not work well.
Finally got the correct ICs but that didn't help, neither did Cary, who treated me like I was asking for the nuclear launch codes.
