F.S. EIMAC 3CPX800A7 “DUD” TUBES: Offering a few dis-functional EIMAC 3CPX800A7 tubes. Great for decorations, paper weight or ornaments on your Ham Christmas Tree in your shack. These tubes FAIL dielectric withstand tests or emission specs, but have working filaments and contain a substantial amount of Copper metal. I would not recommend trying these for functional amplifier use, but could be used for making desk nicnknacks, conversational pieces, possible disectional use, etc. I will sell them for $5 each plus actual ground shipping cost. Payment by personal check or money order.
