VU33 / 10E/9829 diode

Size This valve measures 102x40mm overall and has a B4 base.

This is a somewhat unusual diode in that it has a grid. The base data indicates that pin 1 is either anode, or anode+grid, indicating that there may be two different constructions of this valve.

Filament voltage 2V
Filament current 400mA
Max anode voltage 150V

The filament is meant to be fed from a 2V battery via a 0.75 ohm resistance. If extra bias is required a 0.25 ohm resistance can be introduced into the Filament -ve connection.

Pin Function
1 Anode, or Anode and Grid in parallel
2 n/c
3 Filament -ve
4 Filament +ve
VU33
