Use an insulated screwdriver. Works 60% of the time, 90% of the time

Just unplug the amplifier and clip an alligator clip from pin 1 V1 to chassis ground and keep it there. The series isolation resistors will slow the discharge of the filter caps and the gator clip assures nothing builds charge while you’re waiting on parts. Just don’t forget to remove it post cap replacement and first turn on.
After replacing the caps be sure to measure resistance from pin 1 V1 to ground. It should read OL or open. Also don’t add a ton of solder as it will melt through to the bottom of the board and short the stub to chassis ground.

Same here! I dont even want to know how it all works.
I really just want to know how to do this specific task. Lol

isnt there a way to do it by strumming your guitar with a speaker cable plugged in but not connected to a cab with the amp off or something??

Pay someone. You have to know a good tech.

It's both easier and safer to just drain it with a alligator clipped wires. I have a bunch around with 10 W resistors soldered on and just clip them to anything I'm concerned about.
If you have a steady hand, that's a quick-n-easy cap swap. If you're less certain, don't burn the board. That becomes a real problem.
