The right channel output is 1/3 of the volume of the left channel. does anyone have a clue as to why this might be.

Hi! At first check the contacts (in junctions, wires, soldering etc) on the entire path of the signal. At second you should check the electrolythic cap's. It will be better to use oscilloscope in a due to locate the mailfunctional part of schematic. It is the reason to check the signal levels of the both channels beginning from the input. Such way you can find where the signal goes down.

Good luck!
