With all this attention to the 5100B, I would like to know if anyone
has a scan of the dial scale, or know if anyone makes a replacement?

Yes there is a plate current position and it shows a definite rise
in
current with modulation. There are dual 5U4's in the supply
feeding the
finals and modulator and I swapped them both out with the same
results. I am
leaning towards Gary suggestion that there is an impedance
mismatch causing
excessive current draw. Does anyone have a 5100B or know what the
impedance
of the primary and secondary should be. I will try another set of
caps this
evening when I get home there are 2 , 40uf in series on the B+
line.
