Working on a Williams Jokerz and was wondering what causes the strange sounds when powered on. And before anyone asks, im wondering about the sounds before the "factory settings" sounds. Here is a short clip(click the picture):

Sound mod to the CPU has been done. ROMs are all updated to latest versions. All sounds are present in test mode and work fine when game is played.
Now I have had machines in the past make odd noises when powered on and off but nothing like this.
