I just picked up one of these and it sounds pretty amazing. The person before changed a couple caps and eliminated the wiring to the switch for the coupling caps. Also, the bias switch seems to produce a duller sound when put on aggressive.
My question is, can someone provide me a wiring diagram? I'd like to confirm nothing has been connected incorrectly and might just hook it back up to the factory arrangement

Thanks in advance.

PS - using it with a Theta transport/DAC, Bryston amp, and Apogee Scintilla (1 ohm) speakers. Breathtakingly transparent now!

Thanks again!
