I have some Star Synares. Which model used the filter you have in mind? I don't
suppose you happen to have a schematic around for any of the Synare drums,
especially the one you just mentioned? 

I had access to the schematics several years ago, when I worked as a service
tech for a local store that sold Synares.  I later found out that sometime
after I left the company, they either lost or disposed of all their vintage
synth manuals. That's right, they actually threw vintage-synth service manuals,
(and some now-unobtainable  parts as well) straight into the trash!

Observing a moment of silence...
