Can you do anything to make power tubes last longer ?


Besides using them less.

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 ?

Found them ! Matched quad of Mullards EL34 XF2 is coming this way. It's a little risky because they are not new and the exact number of hours on them is unknown, though supposed to be low enough. Test as strong NOS, as the seller with excellent feedback says. It's always a gamble with tubes to a degree, I feel fine about it.
