First off the fact that Joe includes the schematic for his proprietary board makes trouble shooting so much easier, thank you sir. Verified clean signal generator input to rca jacks, input to control board clean, input both inverting and non inverting pins 2 and 3 on the op amp clean, pin 7 15.1v pin 4 -15.1v. However output on pin 6 was a disaster on either channel, wish I could hold phone oscope probe and take a picture all at the same time. basically a lot of hash and minimal waveform. anyways need to order some op134's.
Can only blame myself, even with checking followed the wrong back plane output transistor numbering sequence and probably stressed those poor op amps by doing so even on a dbt startup. Stay tuned for the next installment once Mouser gets me the op amps.
