I just think i blew my amplifier (Luxman 55A). The wire to the right speaker accidentially touched a water pipe (connecting it to ground), while playing. It gave a loud scratching sound and now the right channel is totally dead. Also the left channel sounds low and sometimes very distorted (but sometimes less).
What went wrong? Should I open and see if something looks burned og should I just throw it away?
By the way somthing makes me wonder. When i found it in thrash not long ago, i took it home, opened it and saw that it was not that dusty inside and the fuses were ok. I turned it on an connected my cd-player. Than when i connected a speaker i heard a POP, and both saw and smelled smoke. I opened it again and stangely i could not see anyting burned or find anything that was hot. I tried it again, and it sounded fine - except from dust in the pot-meters. So i cleaned these and hooked it up with four speakers, cd, record player etc. When i turned it on it went POP again, with smoke and all. But it still sounded fine. So i have used it in my living room since then until today. Is that not strange?
