#100: Repairing a vintage pulse/function generator (part 1)

I got this 30+ years old "Global Specialities 8201" pulse generator / function generator / frequency counter with the description that the lights are on but nobody is home, i.e. no output. In this video, I track my attempts repairing it. Since there are many faults, this is only part 1. I don't know yet how many parts there will be.

PS: Yay! This is my 100th YouTube video ... I better start numbering them from now on...
