I've had one fail on me. But that amp had a loose ground on the cathode. So I'm not sure that it is fair to blame that failure on the tube.How do their KT77's hold up?
Other than that one bad experience, I think that the JJ KT77s tubes sound amazing. No other current production EL34 type tube I have tried touches these tubes sonically IMO.
But, FWIW: I will only buy JJs which have been burned-in for at least 24 hours by the dealer first. I figure that this should increase the chances of the dealer catching a bad tube before it gets sent to me.
