Hmm, now that you ask, Gary, I'm not sure . . . I guess it wasn't with the
B+ turned off, but just idling. You know, the memory is a tricky thing . .
. :-) At least, I don't remember running filaments alone with the plate
caps removed and the interlock open - nah, it must have been with B+
applied.

Duane,
How did you accomplish that ? Did you have the means to shut off the high
voltage ? Did you disconnect wires ?
Did you run them in a test fixture that had only filament power (and a fan)
?
