Right now, I fix things for a small company, usually equipment older than me. Servo amps seem to come up a lot.
My college time was for mechanical engineering, but most of this work I do is electrical. I draw on experience gained from screwing around with electronic stuff at home. I'm by no means advanced, but I can tell a bridge rectifier from a flux capacitor. 😛
The pay is not exactly grand or anything, but it's more than I've ever made before, and the company(ies) is a nice one. The owner is a great guy who does genuinely care about his employees. One you're on the payroll long enough, the benefits do of course start, including fully-paid health insurance.
