My Green stripe Mark III gets more action than my Red.
Simul Class, GEQ.
I'm pretty certain it has most of the original preamp tubes.
Power tubes are probably at least 2.5 years old.
Average a gig per month & some rehearsal time..

How long are you running your power tubes?
 
At the risk of sounding sarcastic...I change them when I no longer like how it sounds... :mrgreen: I've had some tubes I changed after a year, and others (like the ones in my Rev F Recto) that have been in there for 10 years, sound great, and I see no need to change them.
 
Preamp tubes only when there is a fault. Power tubes can last a very long time in Marks as they are not stressed into overdrive and are usually fan cooled. They really can go for years.
 
I picked up a '91 Mark I, had it overhauled in '10 never touched it again 8)
sounds too smooth and polished sometimes is my only complaint. Also, I like
it better with my twin closed-back cabinet.
 
After I find the tubes that work best in the amp, there is no need to change them until they die.
