I had a Zesto Bia 200 Select that ran four KT150s (two per channel) in class A. I lost three of the four in 200 hours or less; one for loss of vacuum and the other two with sparks and loud pop. The amp ended up being too hot for the AZ summers and I sold it with a new quad of KT150s. A costly experiment.

Just think if you had used KT170s! For the 150s to blow up, something wasn't right? Biasing or tube selection was off? Pity for such an expensive amp.
