I purchased a used Clearaudio turntable and inadvertently broke the wires inside the arm when assembling the arm to the base.

Spent several hours attempting to repair (solder) back on to the shielded RCA cable as well as to the short wires that clip onto the cartridge. Needless to say, after my handy work, the extreemly thin and delicate arm wire is now too short (after breaking it numerous times in attempting to strip the insulation off and solder).
Where can I purchase GOOD quality cable (color coded; red, white, blue, green and black) to replace the ones that are presently too short? Any suggestions on a good source to send my arm to to have the cables properly replaced? Any other suggestions that may help my situation?
