Should I upgrade my Tubes

I have a Rogue Audio Magnum II which is 100 Watts per channel paired with Vandersteen Treo CT speakers. My tubes seem to be shot as suddenly I get no amplification (just very low level audio). The 4 power tubes are TUNG-SOL KT120. I have been reading about getting "better" tubes but every discussion seems to get into "depends how you like the sound" types of comments similar to every other audio component - LOL.

So what's a man do ?

I fixed it, my bad. I am totally digital streaming and I have a Codex which I guess I accidentally put in Preamp mode. Changed the setting and everything worked. Cost me 2 days of lost pleasure though.

I may punish myself (sic) by spending $ on another set of power tubes (as a back up) and enter the world of tube rolling. Any solid suggestions for listening to blues guitar, jazz and chicks singing ?

Also, do I need to be concerned about the 5 preamp tubes ?

After some research and calling Nick at Rogue Audio, he told me that the biggest impact will be by tube rolling the center (of 5) preamp tube 12AU7. He mentioned the Mullard 12AU7 NOS made in England for the military. Anyone have experience with it ?
