Hello!
After years on the fence, I finally got myself a Roland CM-32L MIDI module.
I knew it was in working condition, but decided to take it apart and have a look at the board just in case.
While the board looks very clean overall, 5 electrolytic capacitors have some kind of solid substance under them. See pictures below.
I've never seen capacitor leakage with my own eyes, so I'm not 100% sure if they indeed are leaking, or if this is leftover flux or glue.
There seems to be some oxidation on the solder joins covered by the gunk. On the other hand, the capacitors are not shorted, and the MIDI module works just fine, outputting very clear sound.
Does anyone with more experience than I do have a clue?
Thank you!
