JanW has used the Part Ninja to rescue a PM5132 function generator:
Today I put the Part Ninja to good use, it came in handy when I was troubleshooting an old Philips PM5132 function generator.
While I was working on a project I wanted to take a break and switched the signal gen off, later that day I came back and the damn thing failed on me. I switched it on and the only thing I got from it were -22 volts at the output. Luckily I had disconnected the circuit under test or it would have gotten fried as well.
