Bally Nip-it Ball count unit issue ultimate repair UPDATE

I've been playing alot of Nip-It lately. I've been testing the delay unit I installed and so far the ball count unit is working perfectly. A few 100's of plays and all is good.

I did make a modification to my delay unit circuit. Playing the game, I realised that I didn't need 2 seconds of delay for the balls to reach their trough switches. I removed the second 1000 uF capacitor, dropping the delay to approximately one second. Plenty of extra time.

Here is an updated version of the delay unit diagram.
