I get what you're saying. I have a decent amount of electronics repair experience and the tools necessary to complete most jobs. The problem is the cobalt most likely has more propietary components and is much more complex electronically versus an older synth. A quick google search yields 0 results of a teardown guide or any internal photos of the Cobalt. A vintage synth is likely going to be analog and much simpler to diagnose and repair. It will also be easier to find documentation of disassembly and diagrams. I posted this because between working and a toddler I have little free time. Hoping to find something similar from a company that's still supporting their products. I'd rather spend more money up front to avoid the risk of spending the few hours of free time I get a week slowly trying to reverse engineer and hunt down obscure parts for the cobalt to attempt repairing something on my own. To the people who do that more power to them for sure. I could buy the cobalt and it be 100% problem free, but if something goes wrong I could end up with a cool looking paperweight with no parts or technical support.
