Bartokfan...KT-88's and KT-90's are two very different tubes. Compare the KT-88 with the winged C 6550 insted. KT-90's to my ear are much more punchy and a bit more agressive then the winged C 6550. Usually KT-90's have a bit more output as well. What was the tube your Jadis amps were 'voiced' with? BTW as far as I know Jadis does not make their own tubes and buys them from China, Russia, Yugo. etc. G.Garfield
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!
