No matter what tubes will go faster turned on.. and preamps do draw a bit more than a dac or CD player and have more dangerous levels of heat in most cases.. Mine takes about 20 min tops to warm up and sound pretty much best after turning on.. this took about 100 hours of listening before it sounded that stable on new tubes however.. But short answer, turn it off, cause even if the tubes last for 4 years running 24-7, vs. only on for 2 hours 3 times a week will probably get you 10 to 20 years on the same tubes.
Tube pre-amps: turn off when not in use?
I just recently purchased a BAT vk-31se - my first true tube product (aside from MF tube buffer). I normally keep all components on, day and night. Was just wondering if any of the more experienced tube users turn off their components when not in use to increase tube life.
Thanks,
