New KT150 tubes?

I have Ref 250 and my dealer told me I can just swap KT120s with KT150s without any modification . I am going to do this pretty soon.

Veerapaneni, has your (ARC?) dealer been given *Official* sanction from ARC Central for the utilisation of KT150's ?

Does anyone know if you can put the 150's in AR REF 210 monos.

@Tsushima1

yes. That what he told me . He went for training to ARC couple of weeks back, and you have to just swap 120s with 150s. Nothing more to be done. I am going to do that soon , My tubes only have 700 hrs and thinking twice to waste them :)

Veerapaaneni ... I e mailed ARC about using the KT-150s in the current Ref line and whether the GS-150 (soon to be released) and the Ref 150 have different innards. So far, no answer.

Here's my cynical speculation. I think the GS-150 WILL sound better than the Ref 150 only because it uses the KT-150 tubes. Otherwise, until someone tells me that the GS-150 has different innards than the Ref 150, I think it's just a dressed up Ref 150 with KT-150 tubes.

I hope an ARC dealer or ARC service tech catches this thread and disabuses me of my cynical comments. I WANT to be wrong, so please someone disabuse me. But so far I see no rational reason for ARC continuing to be officially mum about dropping the KT-150s into their current Ref line. In the meantime, I wait.
