AT 3060 Phantom powered tube mic.

How do you phantom power a tube ("valve", aka.
"firebottle") device? You can't draw enough power
through the 6.2K resistors to heat up the filament?

You can run some tubes on 48 volts, and it is permissable to use DC-Dc
converters.

All true. But it doesn't explain how to get enough POWER
through those 6.2K resistors to heat up the filament?
