SFC repair needed - very low left channel audio

[jperryss]

Hi all. I have a model 1 Super Famicom with almost no left channel audio. I don't hear anything with just the left side plugged in while playing a game. Using the hardware test rom, I can hear the voice sample but it's very quiet (at max TV volume it's as loud as right channel is at maybe 1/4 volume).

Anyone here that can repair this it? I did some searching online but honestly don't trust myself with a soldering iron. I could open it up and snap some pics if it might help.
