Midway Space Invaders faint sound

[s***@gmail.com]

Hi group!

I have a Midway Space Invaders that works like a charm except for one little detail...

The "Invader hit" sound is veryvery faint. If I put my ear to the speaker I can hear the sound, but it in the mix with the other sounds it is too low to hear.

So I guess it is some kind of amplifier problem and it must be in the specific "invader hit" section since all sounds mixes together in the end (I think).

I have changed the 3900 at K4 and K5 (plus a few others) and the 7417 at F4 and the 4016 that seems to be involved.

Does anyone have a little clue that could lead me to the right direction? Do you need more information? Please tell me if so.

Solved, it was a capacitor that was the problem.
