Wink's Tic Tac Dough, the sound effect whenever the board shuffled either the categories or the bonus game amounts.
Also, when there was a dramatic main game win either with a huge pot being won or when a car was won, especially when a car was won...the win cue would play twice and in the middle of that tune being played, the third X would fill in on the board and the "ding" sound...just was super awesome to me as a youth and still is today!
