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

    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
