I used two tall cans as props, and aluminum foil in between to catch the nasty stuff. Lots of tar came out. But the parts separated inside, and were in fact not as one blob, and each one was too light to fall on its own. But came out easily once pulled, almost no effort.
Did propane torch do anything to the surface? It is tinned I think.
Interesting thing about the capacitors inside the block. When I cut them off (this time I did not desolder the wires coming from the radio; I l only cut off the internal wires coming out and then pulled the can; this way I will not have to re-solder the wires back or even to remember in what order they were, and it looks better - undisturbed original soldering), I measured the capacitances. Both high-voltage 1uF ones were fully open, that is in a few nF. And I did make sure there was a good contact when measured. The 0.13uF was also open.
But the 1.5uF one, that is at the ends of the big resistor, between the centertap of the xfmr and the lower end of the field coil was alive and showed 1uF. Funny!

People who do not drink, do not smoke, do not eat red meat will one day feel really stupid lying there and dying from nothing.
