Seems to be a constant problem with these expensive Chinese output tubes (Treasures, PisVanes). They sound great when they are working but just don't seem to be reliable over a reasonable period of time. I have never had trouble in the Rogue until I started spending stupid money on these fancy Chino output tubes. I'm done with them and do not recommend them to anyone. For that kind of money go vintage (GE 6550, EI KT90, SED 6550, GEC KT66, etc)
The good news? I replaced them with a quad of the Penta Labs KT88SC that I have had for years but couldn't seem to make it back into my amp because of these new fancy tubes. They sound great (different than the PisVanes but in the same league) and have always held perfect steady bias. They must have over a thousand hours by now.
The Gold Lion KT66 also sound great and have been rock solid in the Rogue. I believe you can use KT66 in your Cary?
Good luck in your search, and enjoy the roll!
