First, shows high B+ to pin 10 on schematic, but pin 12 on connector drawing. Some connector wiring shows jumper to pin 10 & 12. I only measure pin 10 resistance to 6146 plate cap. I assume pin 11 is the low voltage B+. But cannot measure this to 6L6 screens with ohm meter.

I figured out the wiring. Wiekd Elmac wires mod transformer at socket, not internal to the radio. And, some do not show the mod transformer wired at all! For some reason low B+ did not measure to 6l6 screens, now shows resistance- also weird.
