Note:
The JAMMA Connectors used here are right for Gwlynns PCB's but if you are using the original PCBs they will need to be cut short.
AliExpress didn't have grey paddle switches so had to print my own greys. You can either put up with using Red or go to Thingiverse (or this one ) and print your own. Suggest using a resin printer for this as it will come out better.
The PCBs can be made by any mob. JLCPCB have a minimum order of 5 PCBs but were pretty cheap and did an excellent job but freight. Which wasn't cheap. :(
