We had cheap reciever for cheap ceiling speakers my parents had installed about 20 years ago. I hooked up these old speakers to the newer reciever. Well there was about 10 speakers so i blew the reciever. I was unschooled in the load capablities of recievers. (I largely still am) I'm wondering what I damaged when that little wisp of smoke came from my reciever so that if this is an isolated electronic component, i can replace it and save myself some cash. Replys would be appreciated.
