If you want a primer on tubes you might want to read the FAQ section of the Tube Asylum on Audio Asylum. Don't worry too much, just don't leave the amp on all the time.
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!
