i just bought a new tube amp and i know that it needs to be put on standby when it is first turned on so that the tubes can warm up to the optimum temperature, but how long do they need to warm up?
30 seconds to a minute is fine.
Sometimes even less, depending on the amp.
cool, i thought it had to be longer, but i guess not, thanks
And after it's warm enough to use it takes a few minutes of actual playing before the whole valve is warm. Starts to sound good by about the third song.
6-8 weeks EDIT: not really, 30 seconds to a minute or two, i guess.
I normally wait a minute before going from stby to on and do about the same on the power down.
