Bill,
Jeff has been at c-j for many years and is the guy who understands the tech stuff at c-j better than anyone so if he gives advise, it's spot on. I think he's now been promoted to company president. That said, it may be time for a replacement KT120, although they should last longer than a year. The thump and bias issue is a good question for Jeff. Tubes is tubes, they're always a mystery.
Bob
