Hi all, I am looking for the RF output power knob for a Magnum 257HP. It's the small inner one on the top right of the rig. Kind of a rubbery finish to it, mine split in the middle and then I lost the pieces! Anyone have a source?

These came from a ProStar400 or rpsy 485 or the like. Not really rubbery, but not really hard.
The inner knob looks to be spline, the outer knob looks to fit over split type shaft.
Been a long time since I owned one, don't remember the configuration.
You can PM if you're interested.
