    I set the hum balance on mine by ear. I turned it up flat out with nothing plugged into the input & adjusted for minimum audible hum. The pic neikeel posted is the board from my 1987x clone.

    If you have a scope, you could look at the output & do it that way, but neither is critical.

    Thanks for the replies, guys! Once my arm heals up, and I can lift things again (I tore my right bicep tendon 9 weeks ago, had surgery to reattach it 6 weeks ago, and can't even begin strengthening exercises for another 6 weeks :( ), I'll pull the chassis, and set the bias. Then I will A/B the amps again. :D

    Cheers!
