Sorry I’m late to this. The part number for the specific encoder used by Audiotec Fischer is MERPS11-15295. I was unable to source one myself from anywhere in US or Europe. After a few emails to MSC and AF I think they finally got so annoyed by me that they agreed to send me two replacements from Germany at $65 shipping. Between that cost and finding someone locally with the soldering skills required it was almost more trouble than it was worth but I did get it replaced and works like new. If I was doing it again I would just order a new Director off EBay for $300 or so. Yeah, no warranty but I couldn’t justify the $500 I was quoted from the authorized US dealer.
