3-500Z Eimac Tubes
A year or so ago I put out a message that I had a pair of Eimac 3-500Z tubes that were new, but have been sitting in a box for 35 years. Asked a few questions and received a few replies. Pleased to report that the tubes were finally fired up and are working fine. They are dated 1970. Filaments were warmed up for a day and voltages applied by a rheostat, slowly. About 20 years ago I paid $50 apiece and simply let them sit. I have a Kenwood TL-922A amp so now I have some backup tubes. Just a follow-up to a message sent a long time ago. 73 Murray, K3BEQ |
