EIMAC 4CX350A JAN-8321 4CX-350A USED 2 pcs. These transmitting tubes are probably USED, but they appear to be in good condition and could be considered NOS or USED, but we are not sure. They have been stored for a long time, unused, uninstalled, and untested. They have been taken out of the box for photography purposes, but there are some stains on the box and cracks in the internal case from storage. After that, it was stored. Heater electrodes have been checked for continuity. There is no touch to other electrodes.
