You'll want to make sure if that is termite damage that there isn't an active infestation. They may not be native to your area, but there are dry wood termites that live inside the wood they're eating.
If you're any good at woodwork, the cabinet's not too complex to remake. Chances of finding another Stars cab that has a blown out pf seems slim. So you may end up investing in whole game. Find another classic Stern and you'll have to deal with stencils anyway, so why not remake it? Heck, you could probably even repair it with Bondo or something.
I love my Stars, but at the end of the day, they're not super valuable, so take that into consideration before investing much into a new cab, unless it a grail pin of yours.
