Arcam AVR Center Channel

Hello All,

A while back I purchased an Arcam AVR300 here on Audiogon. It was working great until yesterday. I have a suspicion that something happened to the RCA audio input jacks for the center and subwoofer channels during the process of relocating my gear to a new media unit. Has anyone here had any luck replacing or repairing the connections associated with these jacks first hand? I don't think I want to bother with attempting to send it out for repairs as the unit was pretty inexpensive. If the unit is a lost cause, can anyone recommend a comparable or better sub $500 receiver capable of supporting 5.1 sound? I've been using the analog outs of the oppo 103 and no preference toward HDMI support.
