I think that's right. This is a Fairbanks-Morse 5A which I just found the schematic on. I was actually doing ok without it until I ran into some caps with totally faded markings. Really simple design, easy to work on.Someone had replaced one of the 8mfd caps on the field coil with a 16mfd cap. ugh...
