I have a pair of new Svetlana 4CX800 tubes for sale. They were purchased directly from RF Concepts by my late brother (KP4MS, SK) for his Alpha 99. The problem was not the tubes, but the loading capacitor. So he did not have to use them. I can ship or deliver them in Miami-Dade or Highlands counties. 73, Dave, W4DN w4dn at arrl.net
