Thanks nightraven
Looking closely you will all notice the pot leads on the 5200 board are bent around and soldered directly to the runs on the back side of the board. Also notice the Rate and Color pots wrap around from the side of the boardbefore being soldered to the back. On the 5100 board the pot leads run through holes on the board and soldered to the back. It looks like the EMF underwent a major board revision between the 5100 and 5200. Not sure what year that would have occured. I purchased this unit new in 1978 from Music Emporium, if I remember correctly was located in NJ. Does anyone have this revision EMF and if so may I have photos of the board connections.
