Does "valve denudation" involve removing the glass tube? That certainly would have impact on longevity, and thankfully there is little "prescience" in audio, especially since these tubes have been clearly vetted by others. My bet is that ARC has piles of 120s to get rid of before sticking 150s in their amps.
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
