Had this wild old power transformer, forget what it came out of. 25lb thing, big steel can full of oil and copper, spark-plug looking post terminals all over the top. As I recall it has a 1960's date on it somewhere.
The thing had, for some reason, 240/120 input taps, and output taps for every 6 volt interval up to 1:1.
I soldered springs onto the terminals, like the Radio shack "200 in one" learning kits used to have. That transformer was a part of innumerable bodge machines on my desk for 20 years or so.
I think I finally melted it using it backwards as a step up in a spark gap kinda thing. The bolts melted and the gap was no longer a gap, leading to rich chunky amps being dispensed to the limits of that tool's ability.
