Why one channel with a load and the other without?

Did you have the speaker terminals tight (even without wire in them) when measuring? The parts are only in good contact with the actual contact when tight.

Just in order to get both readings. not sure which you wanted. i would assume without a load since your not gonna know what kind of load i'm running. I was measuring on the contacts on the board right behind the terminals.

For all remaining tests for voltage, confirm that you have approximately 1/2v AC at the back of the input RCA jacks.

For U100 and U200, pin 7, what is the AC votlage?

Sorry man, i'm not sure what your looking at for "U100 and U200, pin 7"
Scratch that, i think i found what your talking about, not sure which is pin 7 off hand though.
And are you wanting me to probe from pin 7 of U100 to pin 7 off U200 for that reading?
