I'm actually thinking about replacing the entire driver board with the Alltek board since I have the new Alltek MPU already in there.  Do you think that would be a good move?  I'm not sure what experience anyone has had with the Alltek driver boards.  On another similar note, I had to replace the resistor on the upper flipper with a 10w instead of 5w because it's the only thing Radio Shack had in stock today.  It seems to be working fine, but do you all think that will cause any problems?   Sorry to keep hounding you guys with questions, but this thing is all new to me.  I do very much appreciate you all giving me the benefit of your experience though!
