Alfred,
Not neurosurgery here. You can purchase some raw stock Kimber 8TC and start stripping. Here's what you will run into. The circuit boards most likely have small holes where the original wires went, so you will untangle the braid of the Kimber and use only 1 or 2 wires of the 8 wire strand.
You can also note the values of the electrolytic capacitors, purchase and install equal value prolypropylene or mylar caps which will really help out the imagine, attack and openess of the speaker. Not rocket science. Good luck
