I have HCA-1000A that was fully recapped, but setting the bias is different story. There are two pots per chan. and three test pins. Not only what are test pins for but mine has two / channel (TRV101, TRV102 and TRV201, TRV202). I am assuming that TRV101 and TRV 201 are for setting the bias voltage. What is the other (TRV102 and TRV202) used
Parasound HCA-1000A Modifications
I recently completed some modifications to my Parasound HCA-1000A a few weeks ago, and HOLY COW!!! Now my $300 amplifier sounds like I spent easily 10 times that amount. It's amazing what can be done with a stock amplifier--especially one as good as the HCA-1000A.
Anyway, my question is this: I am thinking about writing a manual about modifying the HCA-1000A and offering it for a small fee--maybe even putting together a "kit" containing the manual and all necessary parts. Would anybody out there be interested in such a manual or kit, or should I not waste my time?
