Farfisa Professional combo organ reproduction slider caps knobs

Description

These are reproductions of the often-missing slider caps used on the Farfisa Professional and Professional Duo organs, the Professional Piano, and the A-73 amp.  Molded of epoxy resin and color-matched, the only significant difference from the originals is that the shaft on the back that fits into the slider itself is epoxy resin instead of brass.  Unless you're extremely rough on them, they should last as long as the originals.  The second photo shows a set of original caps on top and these repros on the bottom.
I've included a photo of the sliders, showing the little clip thingies that the caps fit into.  Align the flat tab on the back of the cap vertically and push the cap down. It should be a snug fit.  If yours are broken, you might be able to get it attached with some kind of glue, but then it would be a problem to remove the top panel in the future.  I'll leave it to you to figure out what works best.
Choose whatever color(s) you require, or get a complete set of four or five for the Professional or Professional Duo.
Fitted into a custom-cut foam-rubber surround, and shipped in a bubble envelope via USPS First Class.  Fixed shipping regardless of how many are ordered.
