Cool Tube

Westinghouse WL-531/VT-141


I got this tube from Bob KD8ACU (one of my professors at OSU). I think this is a tad OVERKILL for my amp project HIHIHI. 50,000v for the plate, 20 amps@11.5v on the filament...OUCH!!!!!!!! The filament takes as much current as my rig does transmitting 100w HIHI. I'm sure this tube could run in the tens of kilowatts range. It was commonly used in SCR-270 radar units in the 40's-50's era. It is definitely a collectors item now! (I have no idea if the tube is still good)

Note: Please don't ask me if it is for sale. This one is a keeper.

Edit 12/20/08:

I tried to light up the fillament on this and there is a short, full continuity, between the leads. The tube is no good.
