Bob, No circuit. It is the retro-fitting of a Vernier Reduction Drive. I had to make a couple of modifications to make it work. I had to make a bracket for each pot so the pot will tune properly. The other modification is the filing of the shaft in a "D" shape to make the set screw stay put. You have to keep in mind that mine is a prototype built out of available materials. You would have to make your own modifications if you use something slightly different.
It looks like there is sufficient interest in this so I will write an article on what I did. Bill Harms Jerry's last name is Atherton. He is from Rice Lake, Wisconsin.
