[Boatanchors] Wanted, Rectifier tube

[William L Howard]

I recently got a WW II era Japanese vibrator power supply. It converts
12 volts to either 100 or 200 volts using a vibrator, a transformer and
a rectifier tube. Tube is dead so I am looking for a replacement tube.
It is a 5 pin base tube, has a 12 volt filament, two plates and a
cathode.

Can anyone suggest a US equivalent?

Thanks,

Bill Howard
