I recently picked up a Spy Hunter upright in great shape. It already had the switching power supply conversion done to it and overall the game play and picture looks perfect. The only problems I'm having is no Peter Gunn music and it seems all other sound effects work but the machine gun sound. Missiles, smoke screen, oil slick , explosions etc work fine just no machine guns.
No flashing LED when put into test mode on the game board. But the LED doesn't light up at all on the cheap squeak board when the game is in normal operation or test mode. (does the game board's LED stay off during game play because mine does?) I am tho getting a crackle thru the left speaker while the harness beside the test switch on the cheap squeak board is removed/reattached so I know a signal of some sort is going thru to the speaker. I checked the left speaker volume knob (made sure the wires are still connected) and no audible change is happening, just silence. The right speaker for sound effects seems to function OK other than the missing machine guns.
I checked the voltages on the switching power supply and everything from what I can tell seems to be in the proper range of what I've read here with other Spy Hunter recommendations.
Would the main culprit be the cheap squeak board itself or one certain component on it for the lack of theme music?
And what should I look into for fixing the lack of machine gun effects?
One other thing I noticed was a possible problem from with the lamp driver board as I was getting some bulbs to stay lit such as "oil slick" for no apparant reason and now after swapping some bulbs around I get no lights at all. I do see some possible blown bulbs tho.
Could these 3 possibly be connected with a voltage issue or am I looking at replacing/repairing 3 boards (cheap squeak, lamp driver and the amp/effects board) ?
Other than these issues, the game and controls play fine.
