UA doesn't supply schematics.
How about drawing out the circuit and share how they get -165 dB  EIN ?

Almost as interesting as measuring -154 db THD on an A & P analyzer.

I got a  stuffed ua 2108 board off of ebay. I got most of it figured out as far as, what the transformers are and where the wiring goes but theres a couple of things that I dont understand.  If somebody has a power supply that can give me the pinout info that would help aswell. Here's one of the pictures I got off the net.
