Sony Mega Watchman FD-500 story

[Dan Schafer]

Hi All
A friend of mine gave my an old TV he found, a Sony Mega Watchman model FD-500, circa 1989. Well the thing had a cockroach nest in it....UGH! Got rid of the roches (long story), brought it up on my variac and it worked fine. The frustrating thing is that the two knobs for the volume & tone have their "inset into small trimmer pot slot tap" , tip broke off. The Knobs will not move the pot wipers. How would you Try & attempt to get replacement knobs for this model? I would not have put the time into such a project if I knew. It was still sort of fun with common sense dissassembly. Also has a nice sound. The knobs appeared fine when pulled off , so who knew? I'll also try the AK swap board.
Thanks in advance for anyone's 2 cents & suggestions
