Anouther good practice with mains power is after insuring the power is off with a meter, turn your eyes away and short it with an insulated screwdriver.


When working with valve amps, it's a good idea to solder up a 2W bleeder resistor with alligator clips wired to each end. (I vaguely remember that just shorting it all the time is not good for some component, but I don't recall what.)

Make a habit of the first thing you do when the amp is showing it's guts, is to clip one end of the bleeder onto ground, and the other end onto the HT node, and leave it there until you want to power it up for testing.

when you drill a hole in a plastic enclosure with a 0.7mm drill bit
don't put your finger behind it.
