Rogue Audio Cronus &/or Atlas owners ... TUBES ?

Hi Lamcam......Which KT-90's do you use ? And, how are they different in the Cronus from the original Svetlana EL-34's ? I'm assuming you have the original Cronus, and not the Magnum version.

Hey Facten..........
I replaced all the small tubes, with the guidance of Nick and Mark at Rogue Audio, as follows : an RCA 5814A in the center gain stage position, a pair of GE 5751 "Goldpins" in the 12AX7 slots, and a pair of GE 12AU7A's in the 12AU7 positions. All tubes are "NOS." This change in the five small tubes created a very beautiful improvement in the overall musical presentation of my system.
So, with all this in mind, and again with the guidance of Mark O'Brien, I'm seriously considering the Genalex Gold Lion KT-77's.

A follow-up........ I replaced the original Svetlana EL-34's with a brand new matched quad of Genelex Gold Lion KT-77's. Absolutely beautiful.....My system has never sounded better !

Three weeks later .... WOW ! I am loving the music !

A year later... the amp sounds absolutely wonderful with the Gold Lion KT-77's.
