My Rava sub amp recently stopped working while it was plugged into Lfe line in the receiver, I then hooked it up speaker line it worked breifly then quit. My question is should I try to have it fixed or should I purchase a new amp.It is at Adireaudio in Wash. state.I am currently waiting for some reply on its condition.It has been over 2 months at location.I would appreciate some websites that are selling good quality sub amp plates or a good location to have it possibly repaired. Thanx
