Your situation is not unique. Could this simply be that the tubes have reached the end of their life? In just the last 2 months I have also had 2 power tubes fail in my CAT JL-3 amps. These tubes just happen to be 2 years old. And with previous ARC amps, after a couple years, I have learned that once one tube goes, others soon follow. If the tubes are manufactured by the same company at the same time, it stands to reason that they should all pretty much fail at the same time. So I suspect you are due for a new set of tubes for both amps.
It's like Ken Stevens of Convergent Audio recently wrote to me: when one tube goes, you should replace the whole set. When your car needs a new tire do you buy only one?
And if tube replacement is only $1060, consider yourself lucky. It's a whole lot more expensive for me!
As for the issue of power conditioning, I strongly doubt this has anything to do with your issue here.
