CR Electronic Design -US/Canada distributor

Dothey have retailers, if so try through them. If you must throw in the towel, try Antique Electronic Supply among other such parts dealers.

If you can't deal with the company, an easier way to do this would be to get in touch with a place like Parts Connection, and replace all of the knobs instead of trying to match just 1. You may find that you like better.

If you need to get some info from these guys, call them and say you're looking to buy something and can't find a dealer. Most likely they'll see dollar signs and try to sell you direct instead of sending you to one of their dealers. In the midst of their sales pitch, slip your question in and hang up when you get your answer. Simply put; treat them like they treat you.
