Details:

I have no idea if theres a tube tester able to test this. I plugged it on a SB-220 and worked fine. If it helps, I will add that with the help of a multi meter, found filaments are showing resistance, but no shorts. There is no shorts between plate and filaments grids show proper continuity their associated pins.

Eimac 3-400Z, Transmitting Tube, THIS TUBE IS BEING SOLD AS USED. No shorts detected between the filaments and grids or plate.
