Evan -
OK, I see them. I can't figure out what they were thinking. There
doesn't appear to be any reason for that, unless the new capacitor leads
weren't long enough to reach the ground lug. Anyway, that's my guess
and I'm sticking to it! :-)

Garey,
These are C34 and C36. They are 700 pf disc ceramic.

What are the two caps you are referring to?
