Can you do anything to make power tubes last longer ?

The 60’s Mac amps also very famous for long tube life… I have some 1965 tubes … Tele that still test well.. 

@whart I need to copy your dusting rigor…. wow…. i would never get away with photo like that…..

So you choose particular amps for longest tube life. That's interesting approach, not always works, though.

No… luck as I inherited the MAC which i abused as a young punk… The Music Reference connection born of my experience selling gear Roger designed and built w Harold Beveridge… also imo a genius… RIP….

mulveling,

Could you suggest particular Amperex EL34 that I might want to try later ?

Perhaps, I should also try Sylvania 12AU7 black plates from 50s as well. What difference would they make compared to RCA black plates from 50s, I wonder ?

Mke sure there all biased correctly.enjoy the tube sound.
