On those Motorola's the caps are the biggest problem. I have recapped a couple and they worked fine. They are good sets to repair. Also, the selenium rectifiers (finned squares underneath) are probably bad. If they "pop" you are in for an unpleasant(!) smell that lingers a looooong time in the repair area. Also, the high value resistors in the sweep circuits need to be checked. I replace them with one watt and it seems to help stabilize the circuitry a bit. Take your time and recap it and it should be a good start. They are fun sets
