One of the first things technicians learn is to always short-circuit capacitors before working on them, so they can discharge. Just use a screwdriver or something conductive across the capacitor terminals. Be careful, there might be sparks or metal particles coming out of it, so you should wear glasses when doing this. wolever said: “The problem is, the capacitor still has a charge in it.

That alone would make me go. ACTIVE SURPLUS ROCKS! - the Photocritic ‘team’ would love to go around there and see what they could round up- but watch out - they have a giant gorilla outside!

Just be careful! There is a store up here in Toronto called Active Surplus which sells everything and plastic baby arms. At one point they had a huge bin of just the flash boards (capacitor, flash and related circuitry). Of course, people would pull 'em out, stick a battery in and try them. Then put them back. The problem is, the capacitor still has a charge in it. I remember sticking my hand in to try and find one, only to be hit by a couple different boards. The same thing happened with my old digital camera when I tried to take it apart... Oh goodness… Just be careful!
