I would amend your statement that Ralph recommends preconditioning NOS 6AS7s
by way of saying that (unless I, myself, have misunderstood) he really doesn't advocate the use of older NOS power tubes (such as the 6080) but IF you do choose to go that route, be sure to precondiotion first.

BTW, I cannot imagine that the Benchmark amp would play in the same zip code as the MA-1s. IMHO.

I don't recognize the 6080 number. I was referring to these GE JAN 6AS7GA tubes at Parts Express. I had about 20% infant mortality (which Parts Express replaced, but even with a 20% hit the effective price is still comparable to the Sino tubes).

  Any 'A' variant will be unreliable!

    Good to know Ralph. Thanks!
    
    The 8 that made it through burn in continue to work well, but I'll stick to Chinese or Russian tubes going forward.

  Sorry but I can't offer anything useful on NOS 6AS7s as I have no personal experience with them. I've stuck to Sovteks all these years except for a brief fling with the Chinese 6N31 variant, which proved to be a bad move.

    " except for a brief fling with the Chinese 6N31 variant, which proved to be a bad move."
    
    I don't remember that. Why was it a bad move?

      High failure rate and short life span...pretty much in line with all of the Chinese tubes I've tried whether driver or power.
