I've done the job several times.
First determine there is sufficient room to clear internal components. The next problem is cutting the chassis for the male IEC.
Supposedly there's a die that will do a perfect punch on the chassis, unfortunately I don't own one. I got it done by tracing the plug outline with a pencil, drilling multiple holes inside the tracing, grinding with a Dremel tool and finishing up with fine swiss metal files.
The male IEC pins are hot, neutral and ground.
The hot and neutral hook up where the old lamp cord went and you can then decide if you want to attach the ground to the chassis.
When I converted my AirTight ATM 3, I left off the ground because it did not have one from the factory. Early Atma-Sphere amps had no ground either but may now.
I assume your doing this for the convenience of detachable power cord and perhaps allow for some cord testing.
