How to replace hardwired stock power cord ?

Hello!

I have an old - but exquisite Nakamichi MB10 CD Player.  I did come across a post - with very detailed instructions and pictures of modifications possible - someone having modified the unit - basically he changed the stock power to a detachable "IEC" connector - changed some capacitors etc ....

Regretfully I didn't bookmark it - and i cant find it now...have searched the net few time... :( bummer!

Would anyone know - how to go about cutting out the original hardwired cheap power cord and replace it with a good quality one ?

Have I posted this under right topic ? 

Any help - much appreciated....thanks
