Did you save that board Richard? Someday another board will blow only.. say the turret rotation transistor. Then you can desolder the one from the board with the blown motor transistors and get back in business. I write down what went wrong with each board and place them in a sandwhich bag and all are in a 1 gallon bag. Unfortunately the bag is getting full! My good board bag is getting light, only 2 spares left!
