Dead 16GP4

I had one like that too, zero emissions no matter how high the heater voltage, wouldn't rejuv, tried it in a set, nada.

I suspect these metal tubes sometimes get a microscopic amount of gas in them and it kills them dead even though they don't glow purple and the getter is OK.

Mine looked like it had been stored very poorly, rusty and dirty, I didn't expect it would work and I was right.
