Just now checking posts. What you've already seen is what I was going to suggest because it's how I did this for someone else here recently. Not your two models but the following two, I think. At any rate, it's the small, more subtle differences that need to be looked for when the basic design for the signal path remains more consistent.Originally posted by nosaj View Post"Take two placebos, works twice as well."

IIRC, on the AB165 the green wire from the OT is grounded and the Black wire is connected to the speakers.WARNING! Musical Instrument amplifiers contain lethal voltages and can retain them even when unplugged. Refer service to qualified personnel.
