Hans,
The trifiliar was one of the first things we did…. Also, I reflowed all the other places where enamel comes thru the board. I should mention that the 1804 gets warm… not hot but warm. I’ll look back try my emails with John and get an idea of where we were, it has been a while since I had the time to mess with it. I would really like to get the original going because it was one from Dayton and then the new one is obviously not. Also… I made a work around but a heads up, my 2X3 female socket connector was missing a pin. See attachment.
