HI
I just got a new power supply for my restoration of Space Gun
The issue I have is that my sound is not working, I got a humming sound.
I have noticed that the negative 5 volt is not present, and it seems that this game uses the negative 5V for sound.
BUT when I opend the PSU I can see that the negative rail is not connected at all!!!
If I follow the trace from negative 5 rail, C20 is missing.
Can i just replace the missing cap wit a new cap the same value 1000uf 16v as used at the normal +5V rail?
