Btselect - Forgot to ask. When you compared the KT150's were they fully broken in? I ask because when my KT120's were new I really liked them. After 100 hrs I had to take them out. Too forward and a bit grainy. I loaned them to a friend who said he loved them. He put about 150 hrs on them when I got them back. I tried them again although better (very linear) I also replaced my driver tubes (Telefunken 12at7's) with some warm sounding Mullards which helped even more but still not as good as EiKT90's.
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
