Thanks for the info Dave.

Here's what I've figured out so far by comparing cards to the schematic. I think you were off by one with your FIL1 & FIL2 chart,

Filament voltage

A9 - K9 = 0.1's
B11 - K11 = 1's
A16 - G16 = 10s

2BN4 - H11 (2) + G9 (0.3) = 2.3 v
3BN4 - H11 (2) + A9 (0.9) = 2.9 v
3CB6 - A11, D11 (3) + J9 (0.1) = 3.1 v (this one is a bit odd, why not use H11 + J9 ?)
4CB6 - F11 (4) + H9 (0.2) = 4.2 v
6CB6 - D11 (6) + G9 (0.3) = 6.3 v
