Thanks, but this one is a full-sized octal can, looks like a 6AG7 only 
larger in diameter.   And the good news is, it works!

Turns out the only problem was not realizing that the DC output of the 
supply was connected to a very heavy bleeder resistor that was drawing 
130mA.   Once I hooked the good old Motorola adjustable DC supply to it, 
the thing fired right up and yes, a 400 cycle vibrator is annoying 
;-)    But the supply will produce 120 volts under that load or 190 with 
a more nominal load, so it's a nice solution for running portable tube 
type gear and the filters inside the Airpax power supply module seem to 
do a good job.

I always get a kick out of DC-DC conversion by purely mechanical means ;-)
