Rogue Audio Cronus owners........new tubes ??


My wonderful amplifier is approaching its "second birthday" at the end of the year, and I know I'll soon need to consider replacing the original Svetlana EL-34's. What have you guys used ? I love the sound of the amp just as it is, but I wouldn't mind "improved sound" if it can be had by using different power tubes.

No one must own any Rogue on this site. I asked the same question about a Metis pre-amp and got no responses. For what it's worth, I have a rebuilt ST-70 that uses EL-34's. I've tried the winged SED " C "s and NOS Siemens. I like them both, the winged "c" being a little more tubey sounding. The Siemens have a more neutral sound with more extended highs and bass.
Adam, I have the Cronus but with the Magnum upgrade so I'm using the EH KT90s so can't help with the EL34 but saw in one older thread that someone was using Sed Winged C's in his Cronus - why not give Mark O'Brien a call and ask him what other EL34s they'd suggest considering.

Would suggest that if you are using the newstock 12ax7s and 12 au7s thatcame with the amp switching them out for some Sylvanias, or Siemens Tungsol combo - can getthem a decent prices and they make a big difference
I am using SED Winged C with my Cronus with great result. Also, I changed the small tubes to NOS.
