Welcome to the Phorum!!

Here's a schematic to start you off http://www.nostalgiaair.org/pagesbymodel...013149.pdf but it will be difficult to read. Do yourself a favor and order a set from Chuck for a few bucks, they are worth it.

Your set is most likely restorable and the cabinet certainly is. Take your time, read first, ask questions. The knobs should pull straight off the shaft. Sometimes they can be stubborn. Some of the guys who have seen 18s before can give you first hand insights. The electolytic caps, all the paper caps and some of the resistors will need to be replaced. The electrolytics can be opened and restuffed with new caps so the appearance of the chassis will stay the same (if you want do to that). There are threads on how to do that on this phorum and Chuck has a tutorial here..

You'll want to check the power transformer to see if the primary and secondaries are showing continuity, similarly check the speaker voice coil and field coil for continuity. Those can be harder to find replacements for.
