    Mine is nothing more than a ceramic light socket and an extension cord with one wire cut and hooked to the light socket.
    Not fancy enough to take a picture of but I spent less time building it than I did writting this post. :)

    All this snow is making me crazy enough to take a pic of my limiter

    Just made mine recently for an amp build. $35 in parts from Home Depot. The scrap 2x6 board was free.

    Are these things really necessary? I mean I've been noodling with tube amplifiers for twenty years or so and I've never found the need for one of these. Surely you have enough confidence in your circuits? Heck, if it blows the fuse go looking for the culprit.

    Lots of bad things can happen to amps that do not blow the fuse. But if you've managed to go 20 years without making any serious wiring errors then no, you don't need one.

    For me, on new builds, the limiter has saved me from some expensive trouble.

    There're way more useful than for checking new builds and cheap to make. Mine was a couple bucks at a junk shop for a used light socket an an extension cord.

    But whatever. I've been fixing old amps for over 20 years with out a scope. Doesn't mean it's the right way to do it. Just means I spend a lot of time finding a problem I could find faster with a scope.

    It makes it easier to find shorts, and I don't need a pocket full of fuses.

    So now you tell me I wasted my time! Guess you don't need a multimeter, scope, variac, signal generator or any other nonsense either as long as you are God's gift to the Amp World! :p

    The limiter has saved my butt a couple times.

    Good luck finding ultrasonics, signal asymmetry and hysteresis without an oscilloscope.
