This is indeed an indestructible amplifier on the TPA3110. They overestimated the supply voltage, they removed very high power from it WITHOUT a radiator, they drove it into such modes that are not even indicated in the datasheet! The amplifier went into protection several times, but at the same time it did not burn out and continues to work! Amplifier on a TPA3110 chip in a bridged connection. Let's check the truly maximum power of the TPA3110!
