vintage
Comments Off
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. This item is in the category “Consumer Electronics\Radio Communication\Parts & Accessories\Tubes”. The seller is “andoesp” and is located in IASI. This item can be shipped worldwide.
