Primer reading for new Rogue Cronus owner?


I just bought a used Cronus (not Magnum), and rather than bombarding you with a million scattered questions, could you steer me to some good, basic info related to regular use, maintenance, problem solving, "tube rolling," etc.? I am new to tubes. I read the 9-page manual, but please tell me where to look next - links appreciated. Thanks in advanc, and happy listening!

turn amp on about a minute before listening minimum and do not play it loud for about five minutes (at least that is what I do).

If you hear any static or other noise turn the amp off, or at least turn the volume down and try to determine where the sound is coming from (and then turn it off if you suspect it is the amp).

The reason I mention this is that if a tube goes bad it could take some components of the amp with it so you have to take it easy if you suspect a bad tube.

Mark O'brien at Rogue is a good guy, call him with questions and enjoy!
I had a Cronus and loved it. Enjoy your time with it. It takes a solid 20-25 minutes for it to sound its best but that doesn't mean you have to wait that long to begin listening.
Welcome aboard! I was a holdout for years,now I could never go back to solid state. Once in a blue moon you will have to replace a tube. Just remember that you have to have speakers hooked up when amp is on or else you can damage amp otherwise just set and forget! Later on you might tube roll just to change the flavor of the sound.

It's not written for Rogue Audio, but has lots of basic tube info.
This is all super helpful - thank you for being patient with the novice. I am reading and learning voraciously! Can't wait for the amp to get here. Just starting from scratch, I also bought speakers today - Totem Sttaf. Impedance for this speaker says 8 ohms in literature, and Cronus can be set for 4 or 8 ohms (according to that literature). I'm assuming that's what I set it for - 8 ohms? Would it matter (dumb question, I'm sure)? Also if you have a good speaker cable suggestion for this combination, I'd be much obliged (not really wanting to spend much more than $200).
