I am at the 1,990 mark on my Ref 150 KT120s and was curious about replacing with KT150s. I called Kal at ARC who has been an invaluable resource in the past. I asked when ARC would be done testing the KT 150s. He told me that ARCs position is that it views the life testing of Kt 150s as a "rumor". He could neither confirm nor deny whether that tube was being tested or if was even being considered for testing in the current line. Of course, he was very polite but very firm. I ordered 8 KT120s
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
