I'm trying to source a dual 10K linear but it needs center taps. I'm not finding any dual pots with center taps. Anyone know where such might be found? Thanks.
Not likely log with a center detent, it's probably linear.
But he wants a hard wired electrical center tap (so 4 terminals), unless he's using the wrong term.
Some preamps did use those.

Using octopart.com, I found that TE Connectivity has a dual-gang potentiometer design
The 27ESA series might do:

Digikey has 48 "in stock/normally stocking" 10K 2-gang pots with linear resistivity profiles:

I found them by using the Digikey filters.

A tapped linear pot was often used for tone controls and balance controls in the 50s and 60s.
The Dynaco PAS-2 even had a tone control with a break in the middle of the element for "out of circuit" at the center.

It's not a retrofit, I want to build a circuit from the new Doug Self book. He specs a dual 10K linear center tap with detent and that turns out to be non-existent AFAIK.
