    Definitely worth the effort imo. Like I said before it helped the ripple. I read a recommendation to add a second small cap in parallel to further reduce the ripple but I haven't done that yet. Maybe your install video can include a test to see if it helps. I think it was the pF range for high frequency. There's a vacant spot on the board if you are game. I guess they over engineered and decided to exclude the second large cap.

      I didn't investigate it, but there looks like a spot for another E-Cap on the opposing edge of that board, that may have a high value bleeder resistor installed in it. I'm not going to go any further with mods on it, because the LC102 itself has some more filtering once it gets inside. It looks like it hits a 0.1uF first, then in and out of an LM317, then a 220uF bridged with another 0.1uF. If it had symptoms of bouncing readings, I'd look into it more, but it seems fairly stable with most measurements.
