This is a good board to buy if you have one of these machines and it maybe common in other models, as you can recap it at your your pace, sometimes a little dusty.

Packed with switches and relays many of which are common in the older Teacs so great for spares.

This board is a little earlier than some in the same series and has a cap attached to pcb bottom which looks a factory mod, later boards do not, probably all boards are compatible as have identical relays and switches
