A very recent comment posted on another forum, Dealer/User location as yet unknown.
"My dealer got confirmation i can use the kt150 in my ref750s. They also suggested i wait a bit because they mention with the amount of tube in the 750s, ARC find it difficult apparently to match a large number of kt150 so far. This would not be an issue with smaller amplifier using less tubes. Not sure what to make of it but i will likely upgrade to the kt150 in the near future anyway..."
