<div class="moz-cite-prefix">On the topic of center tapped pots,
this is the only one I've found, Bourns PTT series:</div>

<div class="moz-cite-prefix">They're 11mm and not as tall as the
typical 9mm pots. I don't love plastic shafts and they have a
little more wobble than I like, but I've used a couple hundred of
them and haven't had any failures.</div>
<div class="moz-cite-prefix"><br>
</div>
<div class="moz-cite-prefix">I was in contact with a Taiwanese
manufacturer who makes a clone to get ones with extended threaded
bushing so they could be used alongside 9mm pots and have the
threads reach through the panel. Min quantity is 2k, though. I
may end pulling the trigger on these though later this year, at
10k or 50k value (linear of course). Feel free to contact me off
list if it's something you'd buy a small quantity of (at least 10
or more).</div>
<div class="moz-cite-prefix"><br>
</div>
<div class="moz-cite-prefix">It's a shame they're aren't more
options for tapped pots. They're really useful for tone controls
and doubling up 2 modulation sources to the same pot.</div>

<div>Todd,

<div>I went through the same while restoring Marshall Time
Modulators and EMT reverbs and compressors. It seems they are
more available in UK and Europe. </div>
<div>The EMT 156 uses 4mm shaft ones too (like that Electronic
Surplus link has), which won’t work for you. I assume you want
1/4” or 6.33mm.</div>
<div>Also good luck finding center tapped pots for the SEM. I
bought 100 way back when Jürgen Haible had a custom run group
buy like 20 years ago. </div>

Just trying to spec out some costs on doing a
reSEMble clone, and damn — these are
expensive. Almost $7 a knob with indicator,
more with larger coarse /cutoff / resonance
skirted knobs: $200+ in knobs alone. FWIW,
These are what Tom Oberheim used on the
original SEM. </div>
