I ran into the same issue after recapping my LC II.
However it was just a bad trace between one side of the 50v cap.
Ran a trace wire & it was fixed.

Just to be clear @zezba9000 and @mitchkramez : you found that restoring that connection restored your sound? I have damage in that area and hard-to-diagnose sound problems that aren't directly affected by the presence or absence of that capacitor (I had sound with the capacitor completely missing at one point, restored the capacitor and got distorted sound, then removed it again and got no sound). I am wondering if my problem is actually related to trace damage in the area that is incidentally affected by the recapping, and if you would share some information about your traces.
Can you (or anyone) tell me if UB10 pin 12 (immediately to the left of the green circle in the picture above) is connected to ground or some power rail? The BOMARC schematic only shows it connected to C22, but there is obviously also connected to a via with no obvious connection on the other side of the board. My via is damaged, so I cannot check.
