IT WORKED!!!  Thank you SOOOO much again, Paul!

My Chroma Polaris is living again!  

The only things I have left to do are mostly cosmetic:

~ Replace a few damaged/bent sliders

~ Find a replacement slider knob

~ Fill in some scratches on the aluminum case

Has anyone found any sources (besides vintage synth part online stores) for replacement sliders/knobs?

Paying $4 + shipping for a single slider knob seems ridiculous to me, haha.
