Are you missing FREQUENCY TUNING KNOBS on your RT-385A unit? Or are broken knobs making use difficult? 

Would you like an affordable option and would be happy with a REFURBISHED USED knob? You found them! 

These knobs, (Cessna P/N: 46715-0000), are USED but REFURBISHED with silver dot button tops. See photo. Knobs with small cracks have been "re-glued" and painted for strength. Knobs are sold here singly. Knobs will come with set screws. NOTE: These knobs are used and may come with slight imperfections. None that should affect their performance.

{ If you would like a USED knob with a non-traditional black dot button top, please see my other listing. }

{ If you would like NEW knobs with silver dot button top, please see my other listing. }

Thank you and let me know if you have any questions.
