The deflection yoke?  There are 7 pins at the butt end of the CRT past the yoke, attached to these pins is a plastic connector on a PCB.  The smoke was coming from somewhere on that little PCB.  I don't want to turn it on again and wait for more smoke to see exactly where it's coming from.  I was hoping someone had this issue before.

I did read something about people having problems with dry solder joints somewhere on the yoke, maybe this is the problem?  I'm not sure which joints commonly fail.

Anyways, thanks to anyone who can give me a clue.
