[NJARC] Transmitting Tubes

[John Ruccolo]

Hi Joe/Folks,

While we're on the subject of transmitting tubes, does anybody have a reasonably-priced NOS Eimac 4-250A, or perhaps 1 or 2 used ones with some life left?

I've got a Globe King 500A that I'm planning to restore someday....not someday soon, however. ;-) I'll start with the DX-100 and work my way up....


Regards,

John
