Thanks SmokeandBeers,
I don't believe there is a write up or guide on making the pots. I had read the following suggestion on the main site's Keeley 4 knob from
Zugenk Zz3 dated February 2017 at 05:57"Got an idea for makung a 150k pot. Take 2 stereo pots ( 100k and 50k ) open both and put off one of the carbon slice of each 100k and 50k, turn over both to their places. Then we got 2 pots of 150k, after we solder four pins and rest two pins.
1--2--3. 100k
4--5--6. 50k
Connect 2, 3, 5, 6.
How do you think ?"
I went ahead and tried it, takes less than 5 minutes and very easy to do.
Here was my follow up to Zugenk's post:"Worked perfectly with the Tayda dual pots. No special tools or worries. Set the pots about midway, use a small flathead to pry up the 4 bottom tabs on each dual pot, remove and swap the bottom wafers, then tighten back the tabs with the flathead or needle nose. Done. Took about 3 minutes 1st time. Nothing flies apart or falls out."
I may have wired the pots slightly different than how he suggested, but works correctly like this - "Wire together lugs 1a,2a,1b & 2b on each pot and connect lugs 3a and 3b to the board"
I have a made a few of these using this layout, let me know if you need help once you give it a go.
