Welcome Shelby. I would make sure that ALL solder joints are good everywhere on the board and as @3M_Audio asked, did it do this before you capped it? I would go over all the solder joints with a fine tooth comb and make sure the board is clean, no broken traces, and no backwards installation of caps. Wiggle the transistors and watch for solder breaks. If there are areas showing heat discoloration, I would check those areas too for bad solder joints and bad components. And when I restore those amps, I always rebuild the bridges. I have replaced quite a few diodes in those M200t’s
