Lee,
When you build with a Black Faceplate, do you send the knobs, out for anodizing, source new black ones, or simply polish the OEM ones,
and leave them natural aluminum finish?
I found a stash at Mendelson's (AKA Mendel-junks) in Dayton, Ohio a few years back. Should have bought all they had. Also bought 5000 silpads the same day. It's a shame they closed as they had teflon wire by the foot.
