Details:

Glass bulb, reduced height WE 357A, containing four electrode sets of 350A, with common molybdenum anode; gold plated control and screen grids. I don't have any way to test it, so am selling it untested for display only. It features gold plated screens and molybdenum plate, is in excellent condition. This interesting tube was used in early radar systems the late 1940s and 1950's.

Four pin base. Would make an outstanding Christmas t. 12.5KV, 10A pulse, 100W average plate power.
