Jay, Thanks for that information.  I appreciate it.   I've got the schematic and like you was only able to I.D. the 120VAC for sure.  The wire insulation is so dirty or faded it's really hard to tell what color most of the other leads should be.  I'll get my meter and check voltages on the other pairs and hopefully not end up doing an involuntary dance!

If you have a 12 volt transformer (a real AC transformer, not a DC wall-wart) you can feed the primary from that and scale the secondary voltages to 10% of nominal which will be safer. Variac will work as well, same idea.
