Have an MFJ-989C antenna roller inductor tuner. But hate the inductor component. Loose contacts, grinding, lots of arcs, plus it takes forever to switch bands / QSY even when it does work properly. Wonder if it would be possible to swap out the roller inductor component with an old-fashioned multi-position switch component that would still handle higher power. Something like the inductor the MFJ-962C has (see picture). Has anyone done this? Would it require additional circuitry, etc?
