[Hallicrafters] round knob for SX25 Super Defiant receiver

[John King]

I need an original round knob for my Hallicrafters SX25 Super Defiant receiver. It is a smooth round knob for the crystal phasing control and is identical to the RF gain and AF gain control knobs. It does not have a skirt. 

Please don't refer me to "parts2many". I will go there if I can't find one from another source.

Thank you very much and 73, John, K5PGW "Old Radio Geezer"
