I am looking at a schematic on a BOSS ME-50 guitar effects box board. It is not powering up with wall wart or battery pack. 9 volts.
It has a capacitor SMD C131 as a filter before the coil before the power on switch. (See schematic). I looks like it has come off the board. The schematic has the C131 and N.I.U. Do not know what NIU means.
