hi i tried to do keeley's mods but when i finished it didn't work!not even when turned off! the led was working any ideas where to focus?
Check out that you replaced the right parts with the right parts. If you stuck in a capacitor instead of a resistor or the other way around, it could cause it not to work.
Check your soldering job. Look at it with a magnifying glass. Did the solder go onto other pads instead of staying where it should have? That's a solder bridge and a common reason for circuits not working.
