Actually you are lucky that the 80 rectifier is missing, as you will certainluy have to replace the electrolytic capacitors at a bare minimum before firing the set up again. Actually there are about a dozen or so other capacitors that should be changed out as well along with out of spec resistors. You will need to get a nice little digital volt-ohm meter (<$20) and a circuit diagram for your set.

None of this is rocket science, or large expense at all, and if you have a little time and interest, we can help you through a restoration. Don't plug it in again so soon.
