I have an old set of Audio Technica AT705 headphones (circa 1975).  Can't locate the original owner's manual and need some help hooking them up.  These are electret condenser (electrostatic) headphones.  From the power supply there are four wires that connect to speaker terminals (Red, White, Blue, and Black).  I'm just trying to figure out which one goes where.

Thanks.

This link from head-fi might help
If there are any 705 owners in here that want a photocopy of the manual I will gladly send them out a copy free of charge when I get these. Just pm me.
