I assume that you are referring to the potentiometer that turns together with the tuning control?
This is a very common problem in all Philips sets of that era. Getting a replacement is something for your dreams, they are very, very rare, even over here.
Your best bet is "robbing a wreck"!
If the damage is not too bad you might want to try the method that has worked for me a couple of times:
Short circuit the "gaps" by inserting small strips of copper between the windings and the baseplate, make sure you have a "bridge" and then glue the strip in place. If you do it carefully not a soul will ever see you did it and your set is back in business. It needs a bit of experimenting with the thickness of the strip but it's worth it.Good luck,
Henk
