I had these running on my Khorns and they sounded perfect. Today they made a little Phoompf sound so I cut them off and hooked up a pair of test speakers. They played fine for about an hour and then they started making a Phoomfp Phoomfp sound again. No smoke or fire. The tubes look fine but it definitely sounds like something letting go.
Any ideas before they see the great trade in UPS truck?

Are these Carverfest amps or are the the new production models just released by Bob. I thought I remember seeing where you traded up.

I would start with the power supply circuit.

Good sound—like good music, good wine and good fellowship—is meant to be shared.
