My greatest triumph was about a year after departure of a former girlfriend who had insisted I move all my stuff out of the garage so her stuff could go in. A lot of it was still heaped into a mountain in the driveway with a tarp over it.
A client brought a failed Telex terminal to see if I could fix it. Bad power supply. I looked at the power supply and it seemed sort of familiar. I dove under the tarp with a flashlight and 10 minutes later everged with a brand new Telex power supply.
The client was impressed (well, so was I). Of course, until that time I hadn't a hint what it was except that it was a power supply and I bought it real cheap from a surplus store. I got good money for it.
