Bad capacitor. i have 5 bad cap (brown color). c725 x 3, c723 x 2, do i have to replace with the same number?


Answers :

You can replace them with higher value capacitance and voltage but not lower. I use good caps made by PANASONIC FM or FC series (105c Low ESR, high ripple current) from DIGIKEY.
