Well, have you had any luck finding the model number on that radio? You might could get ahold of some schematics for it and trace your problems a little better. Even without them, I can tell you that the capacitors in the radio will definitely need replacing. From the looks of it, there's a resistor in that picture alongside what look like a couple of weird capacitors. They look a bit fried to me!

Even without a schematic, you can often read the values right off the capacitors in the radio... providing they haven't melted or deteriorated so badly that the numbers are illegible. I would say that those capacitors are the most likely culprit of your speaker problems, far more so than the resistor. The radio may seem to work right now, and replacing those few bits may very well correct your speaker problem. But... keep in mind that that this should tell you something about the other capacitors throughout your radio.

If you know how to take your radio apart, put it back together, and use a soldering iron, you can probably replace every faulty capacitor in that radio for less than $15. Capacitors are very inexpensive individually and if you order your parts online, it's likely that you'll find dealers who require a minimum order of $10 or $15. So, you'd be a step ahead by ordering all of the capacitors that you need for the entire radio in one stop. There's a lot of great websites that discuss how to "re-cap" a radio, so if you plan on using your Kaiser on a regular basis, I'd recommend reading up on this and deciding if this is something you'd like to attempt yourself. Naturally, you can always ask for help here! It's always worked for me!
