Kevin on the Simple DIY Electronic Music Projects blog received a non-working 1985 Yamaha DX100 synth.
My thinking here is that as it is a pretty nice synth with most of its functionality on a single PCB with connectors to the peripherals, if all else fails I could stick a Pi inside and turn it into a DX100 shaped MiniDexed DX7!
But I’ve decided to have a proper look to see if I can do some “proper” digital electronics fault-finding for once to see if I can get anywhere.
Armed with schematics and other documentation, Kevin goes through the diagnosis.
Here is another repair video Kevin references in his resources.
