The tube does not work, it is defective. Was tested by someone on a transmitter and did not work – possibly the fault transmitter? I do not have the original packaging or documents. Look carefully at all the pictures. I checked with the ohmmeter. Filament = short circuit. On the scale of 200 Megaohms. Filament + grid = infinite resistance. Filament + anode = infinite resistance. Grid + anode = infinite resistance. The item “Vintage DEFECT CPI EIMAC 3CX3000A7 High Power Tube Triode Ceramic VHF HAM RADIO” is in sale since Tuesday, July 7, 2020.
