Along with several others, I am a brand new owner of my first tube head, a Peavey VB-2. This thread is not intended specifically for this amp, but rather pure tube amps in general. I'm looking for advice from those of you who eat, breathe, and while sleeping dream about tubes. Can you list (from your experience/mistakes) some do's and don'ts. The only few I know are: Do: Let the amp warm up for a short period of time (?) before flipping the stand-by switch. Do: Let the cool off in stand-by before switching the mains off. Don't: Turn the amp fully on without a cab (load) connected. Whether or not my VB2 is classic in the making (or like GM's Aztec), I'd like to make sure I get a "lifetime of enjoyment." What else should we tube virgins know?
