Before you actually plug it in, or turn it on, you should have someone who is knowledgeable and experienced take a look at the electronics in it, and at least replace the main filter capacitors in the power supply section. The originals may still be good, but they take the most stress of all, and if they fail, they can cause damage to other parts. They can then also check out all the rest of the electronics to make sure the unit functions as it should. Based on the age, they may wish to also replace ALL the paper capacitors in the circuitry. This is also something we do very commonly in order to prevent problems from developing as these aged parts often fail once they begin to see voltages applied to them again. Usually the resistors and mica or ceramic capacitors hold up better and don't need to be replaced. I hope this helps and saves you problems getting this unit back up and running. Good luck ! And let us know how things turn out.
