I'm sorry!! I was going to spend a few minutes to try to help you out, but it would take more than a few
to trace what you have. I looked at GGG's site and their schematic and BOM and it specifies only 5 capacitors.
Yours uses much more. You did say it was "based" on GGG's schematic, but, apparently there is some modding
going on. Please add more info....working schematic, etc. Someone may be familiar with your project and
jump right in, but they haven't yet. If you give me a little more up front info, I'll try to help.

Beavis has some nice diagrams that show the switch pin numbers. http://www.beavisaudio.com/techpages/Switches/.

Pins 2 and 5 will be the middle pins in each row. Pins 3 and 6 will be the outside lugs. You could also use pins 1 and 4 instead of 3 and 6.

I believe that the above circuit deviates from the GGG schematic as shown below. There are additional low pass filters between Q1 and Q2 that can be switched out.

Good luck with the Ringer project!
