"Thank you so much!!! The new MPU fixed most of our lamp and switch problems and then I was able to fix the the rest of the lamp problems by replacing bulbs, sockets and and a transistor on the lamp board so now Sharpshooter is working 100% for the first time in decades! The family is so happy as the machine was a family heirloom. Can’t thank you enough.
