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

Lissnr, what TRL tube amp do you have? Paul makes excellent stuff that are competitive with anything on the market.
Lissnr, Congrats on a terrific system and I would love to hear it. It's unfortunate not enough audiophiles get to experience Paul's creations.

Actually Xtil6 I have about 200 hours and they are still opening up.I have been told by Paul Weitzel that I should give them at least 500 hours to start seing what they can do. This is not unreasonable since I saw the same results with the KT 120.
1/4 of expected life just for break-in? OK, got a 10000 shares long market order on TS. LOL!

Unfortunately, due to the shape of the KT150 I can only assume that emergency rooms will eventually be dealing with those who've decided to cram them up their...uh...nevermind...innapropriate...sorry...

Fortunately not something you have to worry about ... well broken in with plenty of room. I bet break-in was shorter than your KT120s?
People please do not ask ARC what the status of the KT-150 is. Thanks.
Why?

I might buy a quad of 150s when my 120s die just to see if my amp would blow up. Am I so wrong? Seems the amp (Jolida 502p) can take it...plus I'm getting curious about the 150s and starting to overcome the pickle-esque vibe.
Wolf, proof me wrong that you don't have small ones. LOL!!!
Add the new VAC IQ 200 to the list.   KT88 stock but can roll KT120 and KT150.   

Kevin Hayes said all tests between KT88 and KT150 in the factory and dealer sites, KT88 win hands down.   Very interesting!
