    I had an 18 Farad capacitor for a while. Yes, 18 Farads, not microfarads.

    Not for wimps, it was similar size to a 40 ounce beer bottle and could weld metal when charged.

    If that cap rig is yours for testing purposes, well good luck 🤞

      See that’s “Big Electricity” territory, I don’t go there, it scares me lmao

        I forget what voltage it was rated for, but I think it was over 400 volts. I never charged it up to full voltage though, I just used it as a filter capacitor for an 18 volt document scanner.

        Why? Well I didn’t have a proper 18 volt power supply then, so I just rigged one up by wiring a few random wall-wart power supplies in both series and parallel (don’t ask, it was a mess), to get 18 volts. But, as you’d expect with such a rig, the power was rather noisy, leaving me with really grainy scans.

        So, entered the 18 Farad bad boy to filter the power. Scans came out much better, but I bet OSHA wouldn’t approve…

    In an audio system I don’t think you want big long wires like that… Even between capacitors. Surely can solder all those caps together without long leads? Would be tidier and safer?

      Side test…

      Put a nail in the middle and see how magnetic it gets.

      Hell, attach a paper cone to said nail and see if you get audio out of it.

      Hey, if you’re gonna rig things up for testing, why not have a little fun in the process?
