Call me a rebel CJ told me flat out NO, but I just replaced the kt120's in my CJ premiere 12's with kt150's,60 hours in no issues ,been monitoring the transformers to see if they get hot ,no issues.the sonic difference is astounding in my system.I have had these amps for18 years,and have run 3 brands of 6550's 3 brands of kt88's,for almost 3 years kt120's.I switched to kt120's beccause of better bass and better dynamics,but I always felt they brought a little touch of electronic edge,I didn't know if that was coming from somewhere else in the chain.Back to the 150's,the sound is so dramatically better,I will never go back unless my amps blow up or I do.Dynamics like nothing I have ever heard,no grain or edge,best bass ,best and deepest soundstage ever and most musical
New KT150 tubes?
Has anyone any experience with these pretty new tubes. There are already one or 2 amps I know of, that use them. The review of one of these amps in a UK magazine suggested they were a little warmer and more natural sounding than the nearly new KT120's
The article also suggested they were a straight swap for KT120 based amps, with no adjustment necessary. They are more than twice the cost of KT120's, but still not too costly compared with NOS tubes. I know changing from KT88's or 90's to 120's. did require some amp modification. I have an ARC reference 75 and might want to try the new tubes at some point, ARC don't seem to have a customer E-mail service, to ask the question
