48-1256 alignment help.
#1

Getting geared up to do the AM alignment on the 48-1256 I've been slowly trying to restore.  Never done one of these on my own before, so I've got a few questions.

For reference, here's a pic of the alignment instructions from Sam's:

1. I have an isolation transformer.  Am I reading that correctly that if I use it, I won't need to solder in the .01uf or 200pf caps?

2. What does it mean in the coupling section about high side & low side?  And where do I access B-?

3. Any idea what that smudged section under Output Meter might have said?
