If the rubber mounting grommets are still good, this is a simple fix leaving the tuning cap on the chassis. Use compressed air to blow out all the old dust and debris you can. Place some clean paper towels below the tuning cap. Flood the entire tuning condenser with "Blue Shower" electronics cleaner with tuner fully opened. Repeat a couple shots of the cleaner. Blue Shower cleans and dries fast. Your Done! All debris removed! If the rubber grommets under the tuning cap need replacing to tighten to chassis again, find similar size small rubber faucet washers , drill out the center holes, and fit them both on top & under chassis. The faucet washers can be found in the plumbing departments of Lowes, Home Depot, and hardware stores. Reinstall the new grommets to acheive proper mounting height, and positioning, as required to the cabinet. Blue Shower Electronics cleaners in the spray cans can be found online, or at local electronics wholesalers type stores.
