Quoted from abispac:I have tried with the screw tighted , no diference, and for the capacitor at the speaker, as far as i know is normal, al 3 speakers work right, i even tried using a regular speaker by itself, same result. i took the board with a friend and he checked the capacitors for me, they all seem to be good. so im lost at the moment on what to check next.
Yes, capacitor at the cabinet speaker is normal-at least the same on my funhouse
Altough the one in your pic looks like it got modified/position moved
