I received a new magnet board from a Pinsider and now have a fully working Twister. First time I ever played a game of it with working magnets. I had no idea that upper magnet got so much use. I'm used to trying to see how many orbits I can nail in a row without the ball stopping. A fun game just got even better for me.
Now that I have a working board to compare component measurements, it seems I need to replace the transistors, which is what I was going to do next anyway. Transistors in my board are reading 480 and the new board measures 505. The new board had the service bulletin upgrades done, so I was able to compare the work I did on my board and that looks good. I also replaced a bad resistor on my board.
