Replace the main filter caps. There are also some electrolytics on the circuit boards that should be replaced.
Its also a good idea to remove the power transistors and reseat them with fresh heatsink compound. We've also found it to be a good idea to replace the power cord.
Calibration is not a bad idea. But you'll need test equipment for that- DO NOT try to adjust any of the trimmer potentiometers on the circuit boards without test instruments and the calibration procedure.
