Title: Tube Life
Post by: Canadian Steve on November 06, 2006, 07:07:48 PM

Just wondering how long do tubes/valves normally last before you need new ones?  Do they just gradually deterierate over time or all of a sudden?  Do they last longer if you never crank your amp? :idea:

They will gradually deteriorate and will last around 12 months of regular use for power valves.  Pre-amp valves generally last longer as they're not working so hard.  Cranking will shorten their life, yes.
