external “How to Keep Your Old Flash from Exploding” —Strobist

strobehealthDavid Hobby over at Strobist offers some advice on how you can properly start using an old flash unit sitting in your closet:

“…capacitors (specifically electrolytic capacitors, the type used in flashes) can deteriorate when they go unused over time. As in one inside a your flash sitting in a closet for a few years [...]

In this case, just turning a flash on and waiting a while to “see what happens” is the worst thing you can do. That’s because when the oxide layer deteriorates, you can get current leakage in a fully charged state. Which makes more heat. Which makes more current leakage. “
