I've got a couple dumb questions.

What DC voltage do measure from end to end of the 470 ohm R56?

And from what point have you been getting your B- or ground reference when taking DC voltage measurements? The reason I ask is that you're 245 B+ measured about 25 volts low, and also you mentioned measuring -22 volts at some point.
