EDIT: actually, that capacitor is not extra -- it's simply missing for some reason from my own Mk2 unit here.
Would that be
this capacitor?
From the empeg FAQ:
Now, with all of that said, some early models of Mk2 (not 2a) players were fitted with EMC capacitors that tended to reduce the extreme high frequencies of the front car outputs and the home outputs (but not the rear car outputs). These capacitors were meant to reduce noise, but it was later discovered that they were not needed, and they were removed from subsequent board revisions.tanstaafl.
