Somewhere above I was wondering why my filament circuit halves seemed to be connected to each other AND to ground. Those in the know were polite and made no mockery of the noob- thanks!

Found that: a) The 6A7 socket has a hidden little tab that connects filament (pin 7) to the mounting rivet- and ground.
And b): Of course the transformer secondary for the filaments connects the two sides together with almost zero resistance...duh.

Remember, I'm a MECHANICAL engineer... they did tell me not to stick my fingers inside the electronics boxes...

Achtung! Alles Lookenspeepers!
