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

Comment from an ARC REF75 owner residing in Seattle.

"Call ARC. My dealer did, and they told him to tell me to go ahead and put them in my Ref75."
Tsushima1 .... very interesting bit of news ... but I'm still not dropping those pickles into my amp until ARC says it's ok. Why the wait? Dunno. But until ARC sprinkles pixie dust on the KT-150s ... not in my amp.
From the same, as yet, unsubstantiated source.

Marc, If not too much of an imposition would you mind inquiring, via your dealer, as to ARC's position with respect to the REF150 please.

"I was told that they recommend them in all kt120 based products. But you can also call arc yourself..."

We are still but Agaricus bisporus to the omnipotent Audio Research Company.
