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

Confessions: I don't own an ARC amp, but I approve of them generally, and I'm really in no hurry to try 150s so no amps shall be harmed around here. Also, I check my bias on the factory upgraded (I mention that fact to show I care) Jolida 502p I DO own fairly often for no reason other than I have a meter and enjoy risking knuckle burns. I've noticed the LEDs used for bias setting on this amp are very accurate so really the meter is unnecessary, but I do it anyway...500mv per the manual, and the bias on the 120s stays on track really well, even after over 2 years of abuse. According to the Absolute Sound mag I got yesterday, Jolida just put out a new line of power amps with KT150s called "Luxor", and since Jolida hasn't updated their website since 2004 you have to dig through United Home Audio's site to find anything about them. Somebody get those guys a publicist!

"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.
