I'm curious to hear how many hours of play people are typically getting out of their tubes. Thanks.
It will vary a lot. I've had some last a year or two and others last for twenty years.
I go by this, for power tubes, if you play 3 to 5 times a week a couple hours each jam, you should replace once a year.
If you play less, replace less often, in 35 years of playing, i've never lost a power tube.
Obviously some tubes can last longer, but i would rather keep a fresh quad every year or so.
Pre-amp tubes can last indefinetly, i have some Blackburn Mullards & amprex that are older than dirt, and still sound awesome.
for me,medium gigging just in bars doing covers, amp on from 9.30pm to 2am ...i used to change tubes every may but i currently have JJ 6l6'S in the SLO and ive had em in for 2yrs and still doing good.
depends on the tubes type too,my EL84 amps needed changing every 8/9 months maybe..you can tell when theyre tired
