The horizontal output tube is connected to the capacitor-thing inside, as well as the large tube in the center. The picture tube as well as the capacitor-thing are in a metal cage-box (power supply box -- as I was calling it). Can someone give me some insight on this? This is the box that appeared to be smoking. I'd also like to add that the picture on the screen was blinking while the set was smoking. Is this a whole different problem? Thanks!

The box is most likely the horizontal / high voltage circuit. It drives the horizontal portion of the picture and generates the 1,000s of volts for the picture tube.
That thing with the ring is most likely the flyback transformer. It generates the high voltages. They have a wax coating that can melt and drip over time.
I just happened to have put up a video on YouTube tonight where I go over a late 40s TV and point out what each part does. here's the link:
