Lew,
You are correct about the meter. I set to bias to -20V and then press the offset test button and adjust it to 0.
I was fortunate to receive a message from Matthew Polk of Polk Audio giving me clear instructions on how to do this. Matthew in familiar with the process as he also owns a pair of these amps.
I can get the left channel spot-on but the right channel - not so much.
I hoping that replacing the coupling and other caps will correct this.
Thanks,
