    It's a little late, but he's here. The packaging of such a device is little, but apparently physically survived. One of the mono potency meters was bent only, which was almost a miracle. I haven't put it on yet, because I'd like to go through a microscope and see if there's any damage to the printed circuit. What's noticeable to the eye: The TDA2030, as noted in the previous comment, is instead of the specific LM1875. This IC on 4 Ohm is not 18W, only 14W maximum and the distortion is greater. A good point for its design is the massive heatsink, but the output is not isolated from ICs, so it's on the potential of the third leg. (It's okay, just a note.) No pasting, the screws are tightened directly to cool. This may be worth replacing. I don't have time to test it yet.
