<p>I used Bourns PTH901-030S-103B1. Ideally the shaft would have to
be longer, at least 35mm but I could not find those.</p>
<p>It was impossible to find the original potentiometer with the
built-in reduction gear so I had to improvise... have not done it
yet, but I will add a few resistors to make a "coarse" and "fine"
control in the same pot. Ideally the outer shaft will range from
10 to 90, and the inner shaft will cover the +-10 range.<br>

<p>Cheers!<br>

congrats on being nearly finished. Where did you find the dual

</div>
<div>After dedicating some time to this project, my very own
Memorymoog clone is nearly completed! Still missing the
buttons, so far the 3D printed attempts turned out bad.
Also, the 9mm thickness aluminum side cheeks are not done,
as well as adaptors for the dual concentric frequency
potentiometer knobs.</div>
<div><br>
</div>
<div>It seems to be more stable than the old Memorymoog I
used to own a couple decades ago - no autotune update on
that unit, which is built into my clone. I get "6 tuned"
at pretty much every attempt, as long as I allow for some
15 to 20 minutes warmup.<br>
</div>
<div><br>
</div>
<div>The sound is, as far as I can tell, exactly the same as
a stock Memorymoog: all circuits are exactly the same.</div>
<div><br>
</div>
<div>I tested several LEDs to decide on a color, and figured
the diffuse white looked better than the original red
ones.</div>
<div><br>
</div>
<div>Cheers!</div>
