I have left ONE PAIR of late-date-code, medical overstock, absolutely brand new Eimac 3CPX800A7's, the newer, much more robust drop-in replacements for the older 3CX800's. I can sell the pair for $575 shipped anywhere lower 48. These are the best tubes you can buy, at the best price anywhere. I do not know when I will have more. Many tks, es 73 to all! Jan N0JR
