I modified the machine so that you do not need a large ball catcher box in the back. A smaller container will suffice to catch the ball from the jack pot channel. All of the balls in the playing field that fall into the lost ball hole and into the lost ball channel now come out into the back of the receiver tray. So I just grab a handful of balls and put them into the feeder tray. You need to have an extra small container handy to put your winnings into so you just have to reach up and dump them into the supply tray. If you are entranced in the playing of your game and forget to remove the balls from the receiver tray regularly it backs up into the lost ball hole. If you have a newer machine with a dumping hole from the receiver tray just put your container under that hole. Sure beats reaching around all of the time. I got on a roll and modified old 1960,s 1970,s and newer electronic LCD machines. This makes it a lot easier to keep up with the speed of the electric playing lever.
