I installed some Mundorf caps in my Crack.
A week or so afterwards I did some other mod, and decided to give the joints on the new caps a do-over.
I did not discharge them.
At around 2 am my fiance was awakened by a loud bang and severe swearing.
Everything was fine, the only damage done was to my nerves and my shorts.
After that I made my custom discharge tool from some wire and one of the resistors I'd replaced with a choke earlier.
