Rogue Audio Cronus ..... new power tubes

Adam,

From reading your post I would stay with the Gold Lion power tubes, but what small tubes do you run in the Cronus? If you are running the stock tubes I'd make some changes there. Is there some attribute to your system you'd like to change? Changing the small tubes can make a huge difference.

Hi John .....
I have rolled out all the original tubes, and I think I have successfully modified the amp to give me a better overall sound of music (of course, to my ears and in my room.) With the thoughtful guidance and advice of Mark O'Brien and Nick at Rogue Audio, I swapped out the five small tubes as follows : an RCA NOS 5814 to replace the Electro-Harmonix 12AU7 gain stage tube, a pair of GE NOS Five Star 5751 "goldpins" to replace the Sovtek 12AX7 input tubes, and a pair of GE NOS 12AU7A's to replace the Electro-Harmonix 12AU7 driver tubes. I then replaced the original Svetlana EL-34's with a wonderfully matched quad of Genelex Gold Lion KT-77's.
And ..... I really love the sound of music now, with nothing that I want to change. So, staying with the GL's probably makes the most sense

Adam,

Sounds like you got some really good guidance from Mark and Nick! Given how much you are enjoying your system staying with the Gold Lion KT-77's would make the most sense to me too.

Cheers,

John

Thanks John !
I've been in e-mail contact with Nick at Rogue Audio this morning, and he also recommends another quad of Gold Lion KT-77's. So ..... my decision is now easy. I appreciate your input, and, by the way, my compliments on your system. It must make some pretty beautiful music !

Adam,

It sounds like you have your system dialed-in nicely and i wish you much more happy listening. Thanks too for your compliments on my system, I indeed like it a lot.

John
