[R-390] Kilocycle Dial Tightness (after cleanup)

[Joe]

Same here Al
I finished one in midnight blue, gold front panel plated hardware, and white
glow in the dark UV activated lettering.
Its taken months but sure is sweet.
Even painted 2 marine speakers the match amazing
Taking my time to do the rest and making them nice, its amazing how much
grease build up
they have.
Need to clean them up without blowing up the house with the solvents, brake
parts cleaner, spray gun.
Im in Long Island.
To cold to do outside.....better wait till spring
