My Mesa Hearbreaker was retubed with Winged C power tubes in 2004, still going strong. I replaced all the preamp tubes about a year later with NOS USA tubes, and used at least 20 hours weekly, none have failed.

Many tube sellers want you to change tubes periodically so they can sell you tubes. Carry spares when you gig. Change them when they fail or go microphonic on you. You don't change your light bulbs 'till they blow, do you?

The Mesa Boogie I have is called a DC-5 combo. I bought it new probably around 1993-1995 .... I'm not sure. When I say I had to re-tube it alot I'm probably only talking once a year. I buy Boogie tubes I replace them in pairs.

I think I still have an orginal power tube in my Super. I never liked to replace Fender tubes cause the whole bias control thing always intimidated me.

I have been happy with the Mesa but the amp either practically off or screaming loud. It only has one gear and it is a loud one. :lol:



I think if you gig regularly, a year is reasonable for power tubes, especially if you really push the amp. DC-5 uses what - 6L6's?
Power tubes in my Marshall used to last about a year when I was gigging it a lot.
My Mesa MkIV ran on 6L6's - again, about a year's life. It was my main gigging amp.
It also had a personality similar to your DC-5. It could play at speaking volume and sound great (not loud enough to gig).
Its second sweet spot arrived at a volume loud enough to dent steel...
My Budda Twinmaster - probably 6-8 months of tube life when used at the same pace.
I've a friend who gigs an old Vox AC-30 (EL84s). He probably changes tubes quarterly...

pEAcE,

I never change the tubes in my 60's era blackface Fender Super and Twin. They rarely need it.

For the last 10 years I have gigged with a little 1-12 Mesa Boogie 50w combo. I have put more tubes in that thing than all of Fender Amps combined. I don't know why.

The sweet spot on the Boogie is so freaking loud I am thinking about bringing one of the Fenders out of retirement.


Which Boogie?
I know their .50 caliber (at least the 1st ones) used EL84s (much like their studio .22) that received slamming-high voltages. They pretty much dined on tubes.
I used to own a Mesa MkIV; it needed tubes about once a year (didn't run as hot as the .50 caliber or studio .22).
It's power tubes failed on me at a big gig in NYC; that's when I learned - carry spare tubes
And like you said - you have to push Boogies HARD before they hit their sweet spot - which also diminishes tube life...

Most black panel Super Reverbs and Twin Reverbs weren't very hard on tubes.... most I say. Some Super Reverbs were "King of Kleen", and some were screamers.
I used to have a 1968 Super Reverb (STUPIDLY, STUPIDLY, STUPIDLY TRADED IT - DAMN IDIOT I AM); that was the gnarliest-sounding Super Reverb in creation.
Apparently several of the 1968s were this way - think SRV in a box, no TubeScreamer needed, just turn up the volume.
That Super Reverb also had somewhat of an appetite for tubes, due in no small part I'm sure to the fact that I pushed that amp hard - I put a ClearSonic plexiglass shield around it and turned it up LOUD.
What a great amp.
What an idiot I was for letting it get away....


pEAcE,

jb
