OK, I have decided that I probably will make all new couplates or networks. Not sure of the right name.
My biggest question is what voltage should the ceramic caps be. I've checked with Mouser and it looks like some caps I can only get like 100 volts while most I can get 630 volt or more.
I believe that these are very similar to what the Predicta uses.
Here is a link to a 24x36 schematic which shows all the couplates.
Thank you.
