I have four of these cards, and I intend to throw them into a rack box with some transformers out front. I believe they are +/-15V. I didn't measure the input stage trim pot yet, and I only used transistors that were as close as my simulator would allow... Also, I have the OP transistors wrong, as I couldn't find a place to look up "TO-8" pin config. I just assumed it might be an emitter follower, but since it is supposed to be biased into Class A with a +/- PSU it might be a comp. symm.
Pins:
1) Out
2) V-
3) Ground
4) Input 1
5) N/A
6) Input 2
7) V+
Please correct me if I am wrong on anything here... I am probably going to make it into a mic amp with something between a 1:4 and 1:10 input.
