Do you only want to power the tube filaments?
The filament in the large tube could take a lot of power.

Yes, the power supply is definitely external. I know the socket I currently have the 6SN7 in is not for a tube; I suspect it's for the cable that connects the control head for the unit. As for lighting the tube filaments, it should be doable without much trouble. The large tube (5894A) only takes 6.3 volts at around an amp.
