Hey -
I want to update two old amps by taking out their two-prong power cords and putting in three-prong cords. How's it done? I've Googled it, and there are lots of tutorials for swapping wall sockets, but none for swapping cords.
Thanks!
There could be an issue here. The black conductor's 120-V voltage will now be referenced to the chassis. It's possible for a ground loop to be created with other components such as a phono, etc.

Tell me again why you want to ground a chassis that wasn't originally designed that way?

And, if the receptacle isn't wired correctly, the white wire will have 120-V above the chassis - even worse.

The white wire is neutral. No voltage.
The green wire is the ground.
The black wire connects to the fuse or switch depending on your amp.
