To replace the power cord, the basic steps are very simple. The original two wire cord has a black (hot) and a white (neutral) wire. The new three wire one will have a black and a white and a green (ground) wire. You will just need to connect the new white wire to where the original white wire was connected and the new black wire to where the original black wire was connected. And then the new green wire connects to the chassis ground.

Because the switches on this series of amps are very delicate, I suggest that you be very careful pulling on any of the wires that connect to the switch. If you pull too hard on the back of the switch it will break off at the threaded section, just like your polarity switch.

The ground cap will be connected from the polarity switch to the metal front panel. Cut off the cap at the switch side and then remove the cap from the chassis side. I like connect the new green ground wire to the same spot that the cap was removed from, but your situation could be different. Just be sure that the green wire is securely connected to a clean metal spot of the chassis.

Once the ground cap has been removed, the polarity switch will no longer have any function other than to light up and fill the original hole.

Remember that you are working on the most dangerous part of your amplifier. Work carefully and slowly and you should double check your work before you plug the amp in and turn it back on. With reasonable care and basic skills you should not have any problems doing this change.
