No power supply with it?  Is there a marked connector?  Usually it would
need the filament voltage and B+.  Possibly different filament voltages for
different tubes.  I think that uses a UV-200 or UV201, maybe with an "A"
suffix.

The 200vdc would be a small current, around 50ma max.  Filament current
would be .250ma.  These figures come from a Google search of the brand.

If it would run on 150v, a simple power supply could be made without a
transformer.  Just use a 33 ohm 1/4w resistor as a defacto fuse, a diode and
filter capacitor.  It *might* be able to use a D cell for the filament.
You'd have to do some research on the tube itself.

All of the above could well be dangerous. (Insert usual warnings here)

These things often ran off a 60v or 90v "B" battery and a 1.5v "A" battery.
The 200v for a single ancient tube is rather surprising.  Many places didn't
even have AC power in 1923.
