I used the original Baldwin circuit which I modified with the addition of an .027 uF input capacitor, a dual gange 100K mix control and an output volume control, as well as the switching. I also "upgraded" most of the signal passing caps and I had to build a power supply filter section as I think these units originally relied on the power filtering built into the organ. It was quite noisy without the addition of power filtering caps. I did not draw up a schematic for posterity but below you will find the original Baldwin patent schematic I used for reference.

Oh, and I will add that the enclosure is made from wood which came from a salvage Wurlitzer organ.

Thanks.
As to the patent document I especially like the "Tapered spring reverberation delay line device apparatus".

nothing to exciting, but I built this yesterday to scroll up and down presets on my nemesis without bending over.
