My Spy Hunter had massive sound issues when I first got the machine and I have been slowly bringing it back to life. Now my Peter Gun music plays great and I have all sounds from my main PCB.
To repair the sound I had to rebuild the original linear power supply, replaced all the elect caps in the machine (on all PCBs and power supply) and replace several chips on the cheap squeak deluxe.
Now here is my question - how much static noise (white noise) is there in a properly working Spy Hunter? If I turn both sound level pots down (off) - I still hear some static coming from the speakers. It is not real bad, but noticeable. Is this normal? To be clear - it is not a hum like I also had before, but just some static. I also know it is only present when the cheap squeak is connected.
Thanks!
