I picked up a 600 watt power pack for running those little sidewalk and yard lights. Photo sensor is shot, transformer is massive. Salvage time. But the whole transformer is potted in some sort of black tar. I scraped some of it out, looks like it softens at 200F, goes semi liquid at 250F, and fully liquid at 275F. Easy enough to rig a tent over a catch basin and aim a heater in there but what about the temp rise on the wires? I would need to run it at the 250F to 275F (120C to 135C) range for perhaps an hour to get all the goo out.
