100 ma plate current? Something is not connected correctly?

However 480 ma "A" current would be right .060ma x 8 tubes at full 3.3 volts. Oh! Allow a few ma to energize the "new" meter...

V9 was an early production inclusion. It was eliminated as the model progressed and eliminated entirely from the AC version. If the power harness is correct, the three V9 leads are connected and taped off. Or it is a late edition harness without the leads for V9.

You must connect the harness to satisfy the radio as DC. because of the circuit exchanges in the jumper strip... Those changes must now see the TERMINAL strip as DC...

Might, be powering "B" to only the amp and not the RF/IF stages.
