NOS Russian rectifier tubes B1-0.1/30, anyway know these?

[justanalogue]

As in the title, I bought 2 of them in non electronics store, being sold as decoration items....
Just wondering if anybody here knows them and possibly have schematics of rectifier applications?

Thanks in advance,

Willem.

Not of great use for audio. High voltage and rated for pulse current.

High voltage drop (365V at 300mA) and high filament power dissipation (5V at 5A, 25W) makes it impractical.

But 35kV B+ would be awesome 🙂

30 kV 290 mA steady current rectifier with thoriated tungsten filament. Good for commercial radio transmitter use. Glowing plate, like in TL tubes.
