Hi, My amp got dead after connecting power and I could hear a last sound as something had blown inside but after inspection I cant see anything wrong with the components. I measured and it seems as the LV part of the amp gets 9V power so nothing wrong with that supply however it does not make any speaker sound and the LED does not light up at ON state. I've measured the caps and they do not seem to be shorted. Does anyone have a schematic to share? Any common failures to check? There seems to be another version of SW-112 but cant find any repair videos for mine..
