Hey Don, just curious how you ended up damping the various 'pants you have played with? Prefer not to open these too often if it can be avoided, due to concerns about the wood threading getting damaged. Good stuff, just need to tame the midbass a bit more on mine without killing the low bass off entirely. Currently just have one of the ports plugged.
Repairable, but ouch. Looks like the pads are still somewhat intact, so if you carefully clean the solder out of the real holes with either braid or a pump, you can probably get it to work. Measure your connections after soldering the new parts in though. Also, that cap isnt strictly necessary, you could leave it out without a major problem.
