I have disconnected all speaker wires as well as all other connections. I checked all speaker wires and actually swaped them around to different locations, i could only get the left channel to produce sound. The amp would stay on for a while with the speakers connected but once all wires were disconnected and i plugged it in on the kitchen table it would go into protect mode within a matter of seconds. This amp is only 5 years old and has satisfied my needs for now ,I was hoping to get a few more years out of it.I am hoping to go with a descent tube amp in the near future but I am on a limited budjet,even more now the day i got laid off is the day my amp took a crap.I did notice a hot smell after this all happened i am running a pair of cerwin vega d-9s and a pair of Infinity QBs. Could this be too much speaker for the amp itself? Please dont make fun of me I am kinda of a novice when it comes to this stuff anymore.I used to be big into stereos back in the 80s but alot has changed since then. The technology has came a long way,I am just now actually figuring out everything the hk is actually capable of,and i really think i want to keep it for a while especially since i find myself getting more of my music from my pc these days.I just dont know if its gonna be worth the money to fix it or buy a new amp.Any help or advise would be greatly appreciated.
