I have sound issues. The speech seems ok. The background noise is distorted and it has no play field noise. I have replaced the ROM's and three Op Amps on the music board.,( MC 1458). On thing I did notice is that the -12v is sitting at -14.v? thus the call for a power supply . I replaced the Caps on this one . I reckon ddstoy if you have one I will t buy it off you . It may save me pulling out more of my hair. If you let me know how much and how I will sort it my end. Maybe I am barking up the wrong tree? If so I would really appreciate any help. Another thing worth noting is when i press the sound button on the main CPU the sound is very, very,very faint. It has turned out to be a really great game and would like to get it back to 100% (ish) :)
