I used to dig garbage finding tv, radio, garbage electronics.
Other kids called me "garbage digger". I still do sometimes when I'm around it. About 16 years ago I found a Marantz 2235(I think the model is right) with a 1 bad regulator transistor. Replaced it with a 3 dollar part, voila. I don't have it anymore.
About 10 years ago I found AKAI GX-4000D reel to reel in a garbage heap with just 1 tension lever broken off. A half year ago, I found QSC RMX-850 in the garbage at my work and my boss snatched it away from me. *JERK* I still look for some goodies to work on. But I don't do it as much anymore.
