    I believe there is a Guy on the other forum that tried using the KT150 in his Ref 250's. I'll see if I can find it and post it here.

    The person is Joe Ling. He tried using the kt150. When he installed them, he heard a loud !!!POP!!! and immediately ended his experiment with the kt150's. He said it could have been a bad tube, but he decided not to press his luck. Luckily there was no damage to his Ref 250's.

    Joe...I would not try them until ARC ok's their use. The circuit design, transformer windings, etc...are all optimized for the KT-120s. My guess is ARC is already testing the KT-150 out and it may or may not be a drop-in replacement for the KT-120 in their current amps.

    Thanks guys. I saw that and figured not to even think about it. From what I gather, KT150 are wonderful sounding tubes. I hope they can/will work in my ART monos but will not do anything until proper testing and a go ahead from CJ.

    But those 150 easter-eggs sure look cool. It'll be interesting to see if they end up replacing the 120's in different manufacturers' products.
