    May as well buy 4. They won't be any cheaper later.

    My 572B's are original. Installed 1969. Still put out full power. Even use the amp a lot on AM.
    I must be living good. :)

    When I bought my SB200 it had a pair of Cetron's, but they were a little down on power. I have no way of knowing if they were the original tubes, but I suspect they were. I replaced them with some Taylor's I bought 5 years ago. I've been happy with them.

    Yes...but...

    Nearly 100 bucks each.

    I'm very skeptical of what "matched" means in the context of Chinese tube vendors (if you actually need a matched set of tubes anyway).

    If you are thinking or replacing 811s with 572s, at this juncture, it's a lot more practical just to replace an 811 when one fails (about 35 bucks)...

    ;)

    I think matched means they all look alike.:D

    I have a sneaking suspicion you are right, OM. :D

    Sure.
    Now.

    After I went ahead and finally bought a new amp that doesn’t use 572Bs. ;)

    I thought about replacing my 811s with 572s...but...the 811s are behaving just fine. My inclination would be to use the money they would cost these days toward an amp that a level or two up and doesn't use 811s. :)
