Primaluna and Rogue

Found a great combo of 12ax/au7s.The Mazda 12au7 french military labeled "Cifte" (Quest for Sound) and the Shuguang triple-mica G8/9 12ax7s (probably available thru E-Bay).If you can't find the Shu s,give me a shout.I believe that I might have access to a pair.

Sounds great. I'll post back here after I receive the unit. Thanks for the information. I know nothing about tubes besides the fact that I enjoy the sound immensly. What are the 4 large tubes? I know some tubes last a long time and some don't. Which is which? When I tube roll, do I wear gloves? The owners manual I found on Rogue's website just labels the center as the preamp section. What's the other 2 - 12au7's and the two 12ax7's?

The big tubes are the power or output tubes. You do not want to touch those w/o letting them cool off or using gloves.

use gloves when handling any of the tubes , large or small
The Magnum should have the KT90 powertubes which with the larger power supply allows for the unit generate 90 wpc - these are tubes that get biased . The small tubes are all signal stage tubes

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.
