The Resly Tone RT-18

Below is my transcription of the original Resly Tone circuit. Click on image for the full hi-res pdf document. It excludes the section for the infinitely variable pot on the vibrato speed (in the red box bottom left on the second schematic), which I have put in. This just enables more flexibility if desired. A scanned pdf of the original schematic is here.

Below is the modified Resly Tone circuit with improved inputs and bypass, and a slight correction down the bottom middle in the red box. Click on image for the full hi-res pdf document.
Below is the modified indicator light circuit using a hi intensity LED to replace the inefficient incandescent bulb board. Click on image for the full hi-res pdf document.
