i have a chi coin coney island gun game. the sound card give a richochet sound with a triger pull. the richochet sound is distinct, but the is a gunshot sound that is faint. a video on youtube shows the gunshot sound should be much louder. there is a volume pot, and a tone pot. the pots are good( tested) , but adjusting the tone only makes the richochet sound dimmer. anybody thing changing the caps might help?
