That's the channel that appears to be working OK. There's almost no signal
at all on the anode connections of the other channel, for any position of
VR27A/B, and the channel goes quiet as the pot is rotated clockwise.

There's normal-looking signal at pin 8 of both IC1C and IC2C for each
channel, the op-amp phase inverter, though.

Check X10-X18 cathode ground wire, especially if it is flat IDC cable
(common problem in behringers)

Just curious. What is that thing. I looked at the photo but could not
read the details on it. Is it a preamp or what?
Having both ICs and Tubes is kind of unusual too.
Looks kinda cool, whatever it is.....

You put your sick beats in one end and they sound dope-er coming out the
other
