TIL why skipping the discharge step on old gear is a bad idea
I was working on a vintage radio from the 70s last month (a real beauty, by the way), and I thought I had it safe after unplugging. But when I went to test the power supply board, I got a real jolt from a big capacitor. It stung my fingers and made me drop my screwdriver. After that, I learned that capacitors can keep charge for days, even weeks. Now I use a simple resistor to bleed them off before I do any work. It only takes a minute and saves a lot of pain. I also check with a multimeter to be sure. Don't make the same mistake I did, always discharge those things first.
