Genalex GL KT88 Reissue on Conrad Johnson 12


I am wondering if anyone has had experience with the Gold Lion KT88 on Conrad Johnson Premier 12 or 11 amplifier. Is there any sonic improvement over the stock svetlana 6550 tube, or svetlana kt88 which is what I am currently using.

Also, some ARC owners reported problems with GL KT88 reissue but I do not see similar report from any CJ owners.

Any comments will be appreciated.

What would be a trustworthy source for the Genalex reissues in terms of proper testing and matching?
I am also using these with a VAC Avatar Super,and am very pleased. I got mine from Jim McShane at Citation Amps.

He matches them very carefully, and has a stellar reputation.
I have purchased JJ KT88s and some NOS 62n7s and 6sl7s from TubeDepot &also have purchased Groove Tube EL34s from Virginiatubeaudio - with no complaints -they both carry the Genalex
