well it softened it enough to find 3 through hole resistors loose and somehow the ntc has lost its bead .maybe i knocked it off but i was careful scraping .

Good job, another way to remove the potting mixture is to BOIL it in a saucepan for at least 20 min. I've done this a number of times, best to put in some marbles...to keep the board off the bottom of the pan. It may take a few times, but be assured it works. The problem with solvents can be losing part types.
