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

Spoke with DG at ARC today and he said electrically engineering has signed off A OKAY for use with the KT 150 with the
ARC amps below. But from a Mechanical standpoint one must take note with clearance and observe the larger 150s can vary on glass height with Cages and such could be a close call in some situations etc.
Enjoy, Merry Christmas
