So I'm trying to replace a pot on my 5150 combo, and I pull out the chassis, and remove the screws for the pcb that is folded, but I can't get the pot knobs low enough so I can pull the pcb out. I don't really want to use force, but I don't think I need to remove everything else prior before I get the pcb out. I haven't really worked inside an amp before, so I'm trying to not break something off. I know the caps are discharged, I just can't get this damn thing out!

Any advice would be great.
