    They are in the order of the pictures.

    I used to love Winged C 6L6's but suddenly the price went sky high and apparently they aren't in production.

    Thanks. How much are they going for these days? I'm trying to figure out how to value my amp with these tubes in them. I also have NOS JJ and sylvania 12AX7's in it.

    It's kind of like selling a guitar.

    How much is it worth?

    For NOS or vintage tube pulls, the price will be determined by the demand, condition, rarity, etc.

    You can pay from $15 to $150 for a vintage 12ax7.

    I have seen amps for sale that claim vintage tubes are in it.

    What brand, what year, how many hours on them.

    Best thing to do if you want to sell your amp is do research on the web to see what they are going for, in the same condition of your amp.

    Basically what the market will bear.

    Yeah, I know there will be some variability in the market, I was just looking for a ballpark price for these tubes, which have less than 20 hours of play time in them. Amp is in Mint condition, I am just trying to figure out if having NOS tubes add an extra hundred or two (or 3) to the overall price of the amp. If I won't get the money back out of them, I'm inclined to just keep the preamp and rectifier tubes for use in my other amps (I don't have another 6L6 amp, so those would probably get sold with the 'Verb).

    You don't. If you have tubes with a high value, you pull them and sell them separately. But no one is going to pay more or less for the amp based on the tubes, they have no idea how much life is in them and they may not even be to taste. You don't usually get to recoup the cost of maintenance, mods, premium parts, etc. on resale.

    ^^^ What Wyatt said. You can try and MAY get lucky, but odds are you'll just get the market price for the amp regardless of what tubes are in it.

    People usually keep their quality tubes for their next amp and put cheap modern tubes in the amp they're selling.

    That's what I do. I usually set aside quality stock/modern tubes ans speakers to put back in the amp when I sell it. Otherwise I would be selling ANOS tubes and desirable speakers for less than market value; instead when I reuse them myself.

    Sage advice, thanks! I think I will keep the rectifier and preamp tubes, since I can use those in a different amp. I don't have any other 6L6 amps, so I will probably try and sell them outright. I rarely played this amp to begin with and there's <20 hours on the 6L6's.

    Is there anything people use to test tubes and/or the life of a tube?

    Wyatt's excellent response (#8) addressed the value question very well, but didn't directly address a common and unfortunate misunderstanding inherent in your question.

    When you use tubes, even for only a few hours, you no longer have new, old-stock tubes. What you have is used tubes. They're not the same, and won't be valued the same. Used tubes may be vintage, and manufacturers may be highly revered by some, but they're still used.

    Coming from a non-dealer, your used '80s Mullard CV4024, GE 5U4GB, and SED 6L6GC would be worth less than $100, in my estimation.
