sure, the only problem that folks forget to mention is the chinese tubes are NON rebuildable. I spend my money at Eimac/econco when possible,
I know the response will be "well i run my tubes light and they never will need rebuilding"
What is it that makes them non-rebuildable? I have never heard about any differances in construction etc. that makes them so. Rebuilding a tube should be pretty much universal regardless of who makes it except when the new cost is low enough that rebuilding is not a cost effective approach.
As for dependability, I would take English Electric Valve over even Eimac any day of the week. I have gotten more than twice the life from them in commercial service using 4CX250B, 3CX3000A7, and 4CX5000 tubes than I could get from Eimac even with the exact same operating parameters.
