Help on Audio Research D79A adjustment
Hi everyone,
I have an Audio Research D79 version A with defective preamp tubes. I can't send this very heavy amp to a dealer. I have the schematic and B and C manuals but NOT the A manual There is a procedure to follow for DC balance and distorsion on B and C and I found 3 pots on the A version that I could guess can have the same function. Does anyone have a copy of the user manual of A version that could help me to do it ? Thanks a lot |
