Fun with an old Russian electron tube

I don't know what this tube (RB5) was used for, but it emits a blue light when connected to high voltage (about 1kV). An inverter circuit (for CCFL tubes to backlit LCD screens) converts the 12V from the power supply to high voltage.

WARNING! The voltage used in this video has a very low current, so it is not lethal but it hurts

this tube was either used as a voltage stabelizer or maby a overvoltage protection of some sort. thats the best answer i can give you right now, hope it helps

@lbochtler Thanks! I have the datasheet for this tube but unfortunatly it's written in Russian...

@Fierobsessed Absolutely! ;-)

@helicoptered No. We need to put it on the big boys supply. I want flames!

I think you should crank it up, RIGHT UP on the variac until it POPS... :)

i think this is a rectifier/diode. don't do this too often! it can generate a lot of X-ray!

awesome!
