New KT150 tubes?

Wolfy ... I think what Tsushima1 is saying is that you are a lowbrow. LOL

Not to worry ... my wife says the same about me. ;-)

I only ask that the poster understands the posted words, and at least attempts to use them correctly...example: "potency" makes little sense in the context of this exchange, and "intentional parapraxis" is an oxymoron. My criticism in this case avoids "mixed metaphor" as it is nothing if not direct, and sort of fun...man...I need to get out more...

We have another ARC VSi75 owner, commenting elsewhere, in respect of his unsanctioned adoption of the KT150. He reports that no obvious anomalous behavior has manifest itself,as yet,from either amplifier or himself.

Commenting further, it would appear that he considers the substitution to have been quite efficacious.

"I'm so glad to tell you that this is the greatest improvement I 've ever heard for the money!

Maybe a 15 hours - break in is just a little bit to say that Vsi75 is born for KT150, but soundstage is wider and deeper than ever!

Bass is more bass and midrange is so natural and 3D through my Sophia 3!"

It would be useful if these guys were in a position to monitor bias readings and transformer/circuit temperature.

Perhaps I may make a few inquiries, and post any further information on this point.

Thanks for the update Tsushima. Hopefully Gary (Hifigeek) will catch this thread and post another ARC update on status.

I shall try and ask this week.
