... A 6CA7 with it's 1.5 amp draw might be just
about right  with the original filament dropping
resistors and no ballast resistor. In any of these
cases, the cathode has to be dealt with. It may
work fine to connect it to one side of the heater,
try each and see which works best. 
The alternative would be to use two 20 ohm
resistors in series across the heater and connect
the cathode to the junction between the two
resistors...

Excellent ideas.  Going to try that. Thank you,
Bruce.
