will keep my fingers crossed that these will be better quality and can be used in place of KT-120's. Love the sound of the KT-120 but quality of manufacturing precision is erratic compared to the GL KT-88's they retired for my amp. Given what we saw with the KT-120's no doubt will have to wait a year before the various manufacturers render opinion on whether they are safe to use with the different models in their product lines. I suspect we could all get better results out of an improved QC version of KT-120 (or KT-150 if similar to 120 for tonal balance)
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
