The original had these nifty retractable mini pots that can be pushed in flush the panel when not being used. I cannot seem to find anything similar on the internet. I was wondering if any of you had any inside track into where one might be able to procure such a thing. I need a dozen of them, and I’d prefer if they were PCB mount, but that’s not strictly necessary.<br><br>Thanks in advance,<br>Dave Dixon<br><br>________________________________________________________<br>This is the Synth-diy mailing list<br>Submit email to: Synth-diy@synth-diy.org<br>View archive at: https://synth-diy.org/pipermail/synth-diy/<br>Check your settings at: https://synth-diy.org/mailman/listinfo/synth-diy<br>Selling or trading?
