Zenith Space Command

[Kalamazoo-DJ]

This SS Space Command Chromacolor-II has a very good picture and decent color, I got this from a friend here in VK. But when I play video games such as shown where I am being approached by a hooker and the lettering appears and again where I am running over a guy on the curb the icons on the left hand corner of the screen makes the audio buzz very loud
When I blew up the police car it sounded like it was underwater, any ideas on what may cause this disturbance in the audio it also happens on D-tv when credits are scrolled but not as bad.
