Hello Group, I purchased some items from a closed out TV/FM station. I have one NIB Eimac 3CX3000A7 and one good looking spare. If any of you are looking at building a super amp, this would be the tube, with 4K plate dissipation. I'd take 800 for the new tube, 300 for the spare, or 1000 for the pair. Please reply off list. 73, Keith ve3ts
