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

I think the "don't ask ARC" thing was about protecting the sensitive ARC people from further stress, as Hifigeekl is nothing if not compassionate. I, however, am not. I read in a Brit hifi mag last night that 150s are a "drop in" replacement for 120s, and have a smoother sound...that's what the dude said. The tiny difference in heater requirements make it seem he might be right. I still have never seen anything regarding an amp tranny frying from 120s replacing kt88s anywhere ever at all even once. I'll keep looking.
Anyone have anything to report on pricing. I heard and/or read that pricing could be double that of KT-120s.
I may have mentioned someplace that I've seen 150s on Ebay for around 300 bucks for a quad...that seems almost reasonable.
Tsushima, my eyes ain't what they used to be. I assume you are implying that ARC is hogging the KT-150s for itself? Rats!!! I hate hogs. Well ... I don't feel like getting my head snapped off by calling ARC. Perhaps Gary (Hifigeek) will weigh in again with a status report.
