I bought a sick Alpha 76PA for $600, and had to put a new band switch in it, two wafers. The original tubes were toast (as expected) and I did the simple conversion to a pair of Eimac 3CX800A7 tubes. At 15oo watts PEP, the amp is loafing along, and the two meters, plate current and grid current just slightly wiggle. It is one sweet cool running amplifier. Thanks for the video. Enjoy your 76! 73, de N4JHY, Bruce P.S. I converted a Heathkit SB230 to a Russian GI7b tube for a cool 650 watts PEP on a 120 volt outlet. 73 again.

Where can I get all the information to convert my alpha 76pa over to this tube or possibly two tubes?
