Just as a side bar the model 95 is a very similar set with the same sort of FC set up as a bleeder for the power supply. It's using an 8.3K resistor there. I'd give that a go.

On the old harness I generally try not flex them much while servicing. If it is just few wires I'd use shrink tube over it an leave it alone.

I miswrote -43 is a cap, not a resistor. If 45 is Ok then it should be fine.
All wirewounds are OK?

Are all plate voltages present across all tubes?

Heres what I don't get: high voltage you saw means low power draw. Just the output stage should provide e ough draw.

Ok, resistors 16 and 36.

I replaced #41 with a 800 ohm 10W power resistor and the set works now and fixed all my pin voltage problems. I also rewired the whole chassis to fix all the brittle wiring. I'm kind of sad that I had to lose all that gorgeous cloth wiring but it is safer. My final question. Does anyone have the alignment instructions for this Philco Model 96?

All I can find is this. See page 17

On the page 4 of the Rider's doc is the trimmer's alignment list.
