One thing to check if you are going after a used one. Check the Jack connectors on the backside.
Two on mine are broken, and it is the only thing that is holding the mainboard in place.
I will take mine home from rehearsal this weekend and see if I can get some replacement connectors.
Neutric have some connectors that might fit. Still plastic ( and electrical floating) , but one model with metal nut that’s look a bit stronger.
And yes, just joined a second band, and have started thinking about getting one Mojo more, and this time I will look after one with built in power supply. That PSU connector on the old one is a bit unreliable. Other than that, love my Mojo61, and have found the setting I prefer.
