Re: Roland SC-55 MKII Mini-Headphone Jack Help

So I got around to looking at this, Keropi you were correct that the capacitor looked good even after removing but appeared a little loose.

Re: Roland SC-55 MKII Mini-Headphone Jack Help

If it is glue then the 2200uf cap is the only surface mounted capacitor on the board, perhaps someone can take a pic and we can see if this is normal.

While testing every so often when playing the built-in midi songs the unit would power cycle …

S-MPU/AT BreakOut Box?

Hi all, been creeping this forum for awhile and starting looking around for any Roland stuff in my area. I was able to find a Roland S-MPU/AT for nothing but looking online it appears to be pretty useless without the breakout box for the midi connection. I would be looking to use this with an older …
