Who among us has not purposely hooked up a power
supply to an electrolytic capacitor and turned up the voltage until it popped? It was a ritual for
new guys in the shop. Admittedly, the ones I've blown up were insignificant compared to the one
shown in this photo where the staff at Daven Labs reproduced a test failure and was sure to be
rolling film during the process. Hopefully, no one was in the room either time.
Electrolytic Condenser "Blows Its Top"
working quietly at their tasks at the Daven Laboratories in Newark, New Jersey were startled recently
when an electrolytic condenser suddenly "blew its top." The can hit the ceiling with the speed of a
bullet while paper and foil spiraled upward in a cloud of smoke. Walter Steinhard, Radio News Staff
Photographer, re-produced the phenomena realistically with the original cast of parts.
