Has anyone tried KT150s in their ARC Ref 110?

Bifwynne...thanks for your response.

Joecasey/Wolf_Garcia...please take it offline and just for the record, this thread was specific to the Ref 110 which is not a current Ref amp and hence why I thought it was ok to start a new thread, given that the other thread was about the KT150s in ARC's current Reference amps.

Take what offline? Are we getting TESTY? I did misspell "enough" which is bad. My bad...bad bad bad...

I know the KT120's are OK in the Ref 110. They are said to bring the 110 very near to the 150 in performance. I have heard such an amp at my dealers. Whether you need some modification, I am not sure, a dealer should be able to tell you.

I have had a thread running for months re KT150's in Arc reference amps. ARC are supposed to be doing lifetime testing on this now, no words of wisdom yet

Nothing yet from ARC. I also noted in the other thread not to use the new (if you can still find them)Winged C tubes as their problematic. Use the 6550we instead.

Gary (Hifigeek1) -- fyi. Some many months back, maybe a year ago, I made an online purchase of SED 6550 "Winged Cs" from Upscale Audio. To his credit and honesty, Kevin Deal cancelled the sale because he said there were some problem tubes in his then current inventory of Winged Cs.

I know the original factory that made the Winged Cs in St. Petersberg, Russia burned down a while back. Kevin explained that he had acquired a batch of original Winged Cs. Nevertheless, since then, I buy 6550WEs from ARC and the rest of my tubes from Upscale.

Just re-tubed my ARC Ref 5 SE and CD-8 with ARC sourced 6550 WEs and Upscale Audio matched 6H30s. The rig sounds heavenly. :)

However, my ARC Ref 150 has 1000 hours on its tube set. Sure hoping the KT-150 issue is sorted out by the time I'm ready to switch out the KT-120s.
