OK, I am fairly sure I have my head around it. It would have been easier if not for typos and contradictions in the posted instructions. Also the difference between mono and stereo complicate it a bit.
Johns nice picture is great, but it says TP6/7 when I am pretty sure he meant TP5/6.
The 1st part for the written instructions say to use TP1/2 & TP5/6, with no mention of TP3/4 or TP7/8. Then towards the bottom, it says use TP3/4 and TP7/8 and ignore TP1/2 & TP5/6....
I really don't know for sure which is correct, and why not use all 4 per side?
I think Johns picture instructions are the most easy to follow, short the typo.
If anyone could offer clarification on which TPs to use, that would be great.
It seems clear that you can connect the negative DVM lead to the negative speaker terminal, and leave it there for all testing (per side). The positive would go to the corresponding positive speaker terminal for offset and the "TPs" for Bias adjustment.
Thanks for the help, I am REALLY not trying to be obnoxious.
