My radio required some simple coaxing to get it working properly before I could begin hacking it. It powered on, but had a VERY bad hum that threatened to destroy any speaker connected to it.
Doing my diligent google research, I was unable to find any schematics online and only the tiniest bit of background information on my radio at all. Luckily, you do not really need schematics to do this hack (but it could make things simpler). This site
is a decent resource for information on caps and radios for those that are interested.
In general, the simplest first attempt is to replace all electrolytic and paper capacitors. These capacitors almost always go bad in old radios because, over time, they dry out and their values stray. Replacing them is easy and cheap enough so this can be done very quickly.
In my radio, there are no paper capacitors and only two electrolytics. I used google docs to make an extremely crappy picture with their positions (electrolytics are polarized don't forget!) and their values. I replaced the caps, did a few other minor
things, and it worked! The power cap in the picture was not replaced.
Here is a little video of it functioning:
