Some have reported success at stealing these, or the near equivalents, from scrap PMR sets.

It's also the case that repairs can be made to them but you will need a special bench to heat the ceramic/copper substrate to 150-200C or so before you start. Then you might solder normal joints on top with an Iron.

If the bond wires have gone to the semi chips themselves then I expect you are busted. You can only fix cracks in the matching networks between them.
