Hello,
I have two sound boards both off the 4 board cocktail pcb set with different sound issues. The first one all sounds are good except for the jump sound is real weird. I have read that if it is a 2 board set that wiggling capacitor c24 47UF if the sound changes it might tell you if it is bad . I can not find this capacitor on my 4 board set. On the 4 board set on the sound board the capacitor at c24 is a ceramic disc capacitor that is 0.022 25v
Does anyone have any other suggestions to check on a 4 board set?
My other sound board has missing sounds. It is missing all of the digital sounds like the coin up sound, introduction sounds of the start of the game and probably others I have failed to mention. The sounds it does have are Kong jumping up and down. Mario run, walk climb. The answer to this from what i have read is possibly replace lm324 but I am not sure where that is on a 4 board set.
I am at my witts end with these two sound boards. I have already removed all socketed chips from all of the boards and cleaned them and sprayed contact cleaner in all of the sockets.
If anybody has some information that pertains to 4 board sets it would be greatly appreciated.
