One more thing. When I restarted the project last year my biggest concern was I had errors related to using a 19A1 schematic. My first step was to invent the "Schematic Differential Too." The Rider 19A1 schematic and the Telaides 17T1 were made on the same template. I printed the Rider schematic in red on white paper and the Telaides in black on transparency film. This is how I identified differences in the schematics:

Hence I wired the 17T1 to be in compliance with the Telaides schematic. Except for R41.
Thanks again.
