Primaluna and Rogue

Electro-Harmonix KT90EH is the power tubes that came with the Cronus. The pre-amp tube is a Sylvania. I can't tell what the other two 12au7's and 12ax7's are right now without removing them. I know they're whatever came with it from Rogue. All their web site tells me is that they're upgraded.

I must say, I'm rather impressed with the sound. I began playing music about 10 minutes after I started it up. It sounded pretty good. About 40 minutes later, I was almost in tears listening to the Pink Martinis. I was puuling out CD's I haven't played in years and they all sounded excellent.

Congratulations on your new amp !! I have been absolutely delighted with my Cronus for almost two years now, and I'm sure you're going to be very happy for a long time. And, like I've said here before, Mark and Nick at Rogue Audio are great guys, and are always available to answer questions and give advice. Don't be afraid to give them a call. Good Luck, and Happy Listening !!

Try some Amperex 7025's in place of the 12ax7's.Very nice sounding tube.

Donjr when they shipped me my Magnum all of the signal tubes were Sylvania's , might want to just give them a call and ask

Thanks for all the great feedback. I'm amazed at how beautiful the amp sounds. It's going to make the winter months that much more enjoyable. As I don't know much about tube amps, I was wondering if you could answer a question. If I pull the power tubes out, should I bias them when they go back in? The reason I ask is that since it's a used amp, it was shipped to me with the power tubes out (only signal tubes in). When I got the amp, I just put the tubes in their proper locations (he had the boxes marked) and turned it on without biasing.
