I guess you didnt bother reading and understandng my post relating to the "4CX800A"

It never was and will never be an Eimac product. They are a fraud by several US hams including a former Eimac engineer who decied to revive surplused Russian military tubes, revise specs to their own needs and make a huge profit. That group has long been disbanded and amp owners left hanging in the wind.

You can still buy new 3CPX800A7's from Eimac and Ive had good luck with the Chinese versions built with Eimac supplied tooling and instructors. These can also be purchased from Ameritron when they buy stock for the AL-800 and 800H.

I never got suckered into the "low grid current"  scam.

So, Carl, where would you suggest us cheap, constantly crying, hams get new, or at least new-old-stock Eimac 4CX800's and 3CX800's ? Lotsa luck.

Steve, N2IC

Unlike Eimac, Philips and similar manufactures who design tubes for CCS
service along with plenty of reserve emission to compensate for aging. that tube and most amateur service Chinese are run at the edge. And cheap hams
cry constantly.
