This has only been tested on 1 board, use at your own risk. If you do not get sync, try adjusting R23. Wire up a pot to make it easier. There are now 3 jumpers. These are for a non-pot install. Change R5/R17/R18 to X values. I haven’t done enough testing (only installed in one machine) if these are static for all models.
