As promised, here is a pictorial How To for using a size M or size N (for our purpose, they are equal) DC power jack as a 901 fitting for battery mods.
I got my parts at Radio Shack - part number 274-1583. I have read around the forum that Maplin's has them in the UK.
Here is a pic of the part before I did anything.
The prong at the top of the photo is going to be the positive (+) contact - red wire goes here.
I used pliers to bend the unnecessary prongs back and forth until they broke off. Here is the after pic.
I removed the nut and lockwasher as this space is where I make my negative connection.
Next, I solder on my two wires. The red, or positive (+) is pretty straightforward - just connect red wire to the only remaining solder prong.
Here is a pic of that connection.
For the black, negative (-) connection, I thread my wire through a small gap in the aluminum outer shell, then solder it to the bottom of the threaded portion. Here are a few pics of this to try and make it more clear.
