@Jasper ... not sure I concur with the practical take of your last response. It would be a pure greed play by ARC to withhold the KT-150s approval if they otherwise would not damage the current ref line of amps. Sh*t, who is to say that even if ARC approves the KT-150 that I would buy from ARC .... for $200 a tube. I think not.
Next, my amp was purchased pre-owned from a dealer. Upshot is still no factory warranty. I am dubious that a dealer would go crosswise with ARC.
Having said that, one dealer did in fact post on anther A'gon thread double secret hearsay information sourced back to ARC that the KT-150 was approved for use in current ARC amps. When I spoke to ARC a week or so later, the tech folks denied the bona fides of the report because it came from a marketing guy ... not the tech department.
Go figure.
I'm a big boy. I'll make a decision shortly. If I opt for KT-150s, I'll take my chances.
