John -
Yeah, that'll do it!! :-)
It IS interesting the way that bar in the back is mounted between those
two rivets. It's possible it's a bias magnet of some sort, and then
they lacquer it in place at manufacture.
Important thing is, it's working!!! :-)

*I think Ron and Lee's suggestion is the answer. I tweaked the needle
ever so slightly where the needle takes a 90 degree bend. I was able
to put it dead nuts on. The needle looks straight as a pin. Now that I
think of it I had a catastrophic 6JB6 failure some time ago which most
likely caused the needle to slam hard against the stop which may have
caused the needle to bend. I'm not sure why I didn't notice the
problem then because I had to replace the finals, both screen
resistors, and the meter shunt, reset the bias and re-neutralize the
finals. It was nice to have Garey's CD, I was able to go right to R36
the 2.7 ohm resistor.*
