    Default Who made this amplifier Pi Net inductor???

    Anyone recognize this part, or know who made it and for what amplifier?

    http://www.ebay.com/itm/220837858397

    It was also shown on the cover of the June 1979 issue of Ham Radio Magazine
    along with a few other amplifier components.

    Hope someone knows, because it is bugging me! LOL!

    Yes, That is an AIR-DUX 80-10 meter tank coil. it was used in the Swan Mark I amplifier and perhaps some commercial stuff. I have one here. That one looks like someone redid the coils in gold. Usually they are silvered. Google photos for Swan Mark I amp and you will see them in there. Lou
