Hello Synth DIY Team,
<div class=""><br class="">
</div>
<div class="">As many of you probably know, I am building my own version of the Korg PS-3100. (Here’s a fairly cringe video of the core in action, with a lot of extra info about the board layouts, etc —
<a href="https://www.youtube.com/watch?v=lbtxMdQE64A" class="">https://www.youtube.com/watch?v=lbtxMdQE64A</a>) I’ve got the core circuitry (48 separate synthesizers) and much of the downstream circuitry (resonators, etc) designed, built and tested, and I am
currently trying to lay out the panel.</div>
<div class=""><br class="">
</div>
<div class="">I am going to also have the 12 mini pots down the left side for “TEMPERAMENT ADJUST” (which I presume was basically a way to adjust the tuning without opening the case and adjusting trimmers). 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.</div>
<div class=""><br class="">
</div>
<div class="">Thanks in advance,</div>
<div class="">Dave Dixon</div>
