I noticed our PrimaLuna thread has really started transforming into an all things tube thread, so I figured we could start one of those as a more general thing. So share your love for those little glowing glass cylinders. Share your gear. Share your input. Amps, Pre-amps, headphone amps, phono pre-amps, gear you have, gear you lust after. Let's see ALL the tubes! Ask about tube rolling, where to source tubes, maintenance, compatibility, whatever you want. Go crazy.
