One of the ceramic caps blew on the classic force speaker amp board. Trying to fix it but i dont have any specs on what uF it is. Anyone know?

mahkeymike:
cool thanks

lilshawn:
i removed it an measured it (since i happen have one right here.)

it's 0.1uf

looks like it's just doing some bypass filtering (one side is connected to ground). you may not even need it. remove it and see if it works. most common failure of these caps is shorting out.

Thanks shawn. I think i have some 0.1uf caps in one of my parts bins. One of the traces burned up aswell so i will have to repair the trace anyway so might aswell replace the cap even if its not needed. :cheers:
