Thanks much for all the info guys! I used a hook tool to guide the belt under the capacitor that is on the PCB, got everything routed properly, and installed. It was a bit of work, but not terrible.
I have a few broken plastic parts on this Beocenter, but as of right now, everything is fully working!
