I have two of these amps. One is the original that came with my cabinet, and the right channel doesn't work. The other is a Yaton special which stops working after a minute. Since these are of an age where they could have problem caps, I'm going to put a cap list together and try that first.
Breaking it down, there's an amplifier IC, a handful of surface mount electrolytic caps, one through hole, and a noise filter IC with it's own little surface mount electrolytic caps. And then there's just the connectors, volume pot, and assorted surface mount resistors and ceramic caps.
Edit: I've written down what the markings look like so far. I'm not too familiar with identifying electrolytic smd caps.
