Audio volume is weak from left channel but good from right. Problem appears to be after the amp stage as the problem still exists if i swap the audio in L to R. Also tried swappping the speakers and problem stays with the L channel. It's as if there's a "bad" connection on left channel?

More likley that there is a fault in either the pre-amp or power amp of the left channel. To be honest with you it's one of the most diffcult problems you can have, unless you can see a burnt or damaged part. All you can do is compare the parts in the right channel with those in the left.
Touching the parts in either channel with a screwdriver (don't short any) will cause a buzz! This can be used to test the channels. Work backwards from the power amp section. Remember a buzz in the right should give you one in the same place on the left!
PS KEEP AWAY FROM THE POWER SUPPLY.
