Hi kenny444.. i mean the c7 of surf xx..anyway i made my surf xx working now..i just used an electrolytic cap instead of 1uf stacked cap..

[kenny444]

Hello if your asking about the Surf PI 1.2 pcb capacitor C7 which is 470nF, which is small and quick when passing AC, using a 1uF will take the signal approximately twice as long to charge and discharge the cap, I do not think it will be good.

[jladre]

Can i used a polarized capacitor in C7 which is 1uf stacked capacitor ?? Or is ther any alternative for it? Because I can't find a stacked capacitor in my place.
