I do this to every amp that I rebuid , which is alot of amps....20-30 a year.... I use a Green-lee punch which costs 400.00 to cut the hole ..... I used to do it with the nibbler...I then wire the socket to the two old wires, I then run the ground wire though a switch to the chassis ground.....That way you can switch the ground in and out , which ever works the best for you....
IEC to a 2 prong-wire amp
I dug through some of the old threads until my eyes were aching (**) but I didn't find exactly what I was looking for. Has anyone here installed a standard female 3 point IEC into a amp that originally only had a lamp cord style 2 prong, wire? If so is there some place on the inside for the neutral pin?
