Help with a Bedini BA-803

Hello all,

I recently acquired a Bedini BA-803. I was originally told that the speaker fuse holders needed to be replaced because the sound was cutting out intermittantly. I replaced the fuse holders. The sound is now consistant, but distorted out of the left channel. I have pulled and tested each transistor and they all test good. I am looking for some help regarding what my next logical step should be. i have replaced all the fuses in the amp. The main caps show no bulging. Is this distortion indicative of a bad capacitor? Just trying to decide where to look next. I have switched both the input cables and speaker cables and the distortion follows, so the distortion is definitely coming from the left channel. 

Thanks for any help in advance
