Rogue Cronus Magnum Tube Rolling

Adeep42, why not call Mark at Rogue and discuss with him the sound you are trying to achieve and see if he has any tube recommendations. I don't have my Magnum any longer and preferred a warmer vs brighter sound so can't help you with a tube recommendation, that said I did find Mark very easy to talk to.

What is the amp's current tube compliment?

Thanks all for your input.

Pre-amp tubes:
3 x JJ12AU7
2 x JJ12AX7

Yes. I would suggest putting a Mazda Cite 12au7 in the center pre amp position. I have it in my Cronus Magnum and it's outstanding. Crisp, clean, clear and a very 3D holographic sound without sounding harsh or brittle.

The Cifte is flanked by 2 La Radiotechnique 12au7 in my amp. All from Kevin at Upscale Audio.

I think you would be very happy with the above. You could start with the one Cifte and take it from there!
