Do anybody have any idea in what happened? While waiting I de-assembled the amp. It seems nothing is burned, no traks blown, no bad smell, no signs of something wrong, the chip after the break of the fuses was cold, it seems almost new. really I can't figure out what happened, I can obviously buy another chip (is about 10€, not a big problem) but I want to understand why the last is gone (if is gone).
Just a question, is possible than pressing down the cone by hand this fault something?
