  • Where do you buy capacitors?

    Have a Concorde 2107 with a bad hum. I've cleaned every contact, ready to replace the caps in the power supply/amp. Not finding anything for the big cans. 4000 mfd 50 v, part# 450-010082. I need 4 of them. There are 4 tabs that are ground and 1 +. I wouldn't mind axial, I could make that work. Only thing I can find is with 2 screws. I did find one on Ebay. It said seller refurbished. Is that a thing? Do companies "repack" old caps?

    I use Mouser and Digi-Key electronics a lot. Mostly Mouser because UPS "ground" is actually overnight from Ft Worth to Tulsa.

    Here is an example of a 3900uf/50v "radial" style:

    You have to get creative when searching for capacitors because 4000uf/50v, for example, is not a real common value but 3900uf is. 63 volts may be easier to find than 50, etc.
    Your power supply won't care that is 3900 instead of 4000, but you can go a little higher if you like. Remember, with power supply filters it is generally ok to have a higher capacitance and/or higher voltage rating. Space and mounting considerations may tend to drive your selection.

      Meticulous equipment restorers will put new capacitor inside of the shells of old ones for cosmetic purposes. I don't think that's what you're seeing, and otherwise no, no one rebuilds capacitors that I know of.

        Thank you. Mouser is where I saw the one with screw terminals. Radial is even better. Was thinking axial and if I got that, was going to have to ask, what do you call that plastic tubing you put on wires when there is no insulation?

          Spaghetti.

          For restorations, I get my capacitors from:

            Yep, all my life it was always called "spaghetti" 8) For reasons unknown the manufacturers and catalogs seem to want to call it "tubing", available as "heat shrink" or "non heat shrink" 8)

                    No, In USA. I am 1/4 French Canadian though and I love the Red Green show and Rush. :-)
