[Bill Kinghorn]

Recommendations to "replace the wiring", "the capacitors", "out-of-spec resistors" and the like are horrifying to me. Old electrolytic caps usually need replacing. Some paper caps should be replaced depending on where in the circuit they appear, and should not be disconnected for testing. Any with out-of-spec capacitance would likely be leaking and that can usually be detected with the set ON. Very few resistors need replacement and also should not be cut-loose for testing, most can be WAY out of tolerance with no effect. Wiring, even with brittle insulation, should be left alone, for heavens sake.
