The color code for the spkr wiring is the blue and green wires connect to each plate of 42's. The blue/ white wire connects to the field coil, supplies hv to some of the rf and IF circuits. The green/white wire connects to the ct of the output transformer, field coil and is fed power from the output of the power supply. Most of the time the white wire has turned orange from aging.
As mentioned do check the primary (plate side) of the output transformer. It's not uncommon to have a bad one, either one side of center tap or both.

Vol 1-50 admiring the old set and trying to
figure out what all those squiggly meant.

Now I think I've got!
