The real term is aging, yes then the cathode emission becomes stable and the tube does not drift. The recommended time is circa 36 hours.Me, vacuum tube gear, late 1950's, Stategic Air Command. Delt with tubes. i'm thinking of doing a online consulting service, does this sound like a good idea, to all? won't be free, but i'll teach audio also to component level including transformers.
New Tubes- Need Burn-In?
Hey guys- a question.
I just put a new matched quad of Electro Harmonix KT-88EH in my Cayin A-88T Integrated. I properly biased the amp, and after a couple of hours of warm up there is still a touch of "glare" or hardness evident.
I know these brand new tubes need time to burn in...how long a wait is reasonable before I decide whether the EH tubes are the ticket or not? Any tips on what to expect?
Thanks!
