The nastiest I ever had to do was remove a potted power transformer from a Fisher 70 amp. Yeah the ones with the EL37's.
There were shorted turns on the secondary of the HV winding and it ran really hot and would blow 3 amp fuses.
Anyway I brought it out to the yard, suspended it so the guts would fall out, and gave it a nice propate torch treatment. Took about 5 minutes, and the core and a bunch of tar fell out. Had another tranny that was just about right, and attached the original wires, melted the tar again, filled her up, and I don't remember which set I did it to, I have 4 of 'em.
