Electric Excitement

Blown Capacitor

Andy reports from his workshop:

I was using a old bench  power supply to power some led lights, 12 volts ~<6 amps "Bang"  a gunshot rings out,  the lights go out.
Acrid  grey smoke billows from the power supply.
The power supply  post mortem  shows a capacitor, the size of a old film 35mm film canister, with its guts blown out.
The date on the power supply shows 1959.  The capacitor now costs $35.
