hey, e-man, I have 2 different mph1 prints one that shows the k55 input with a r18 resistor in front, and one that shows no resistor. Is this noise suppression circuitry something that was added on in the field, or was it added to newer mph1 controllers in the factory, or maybe both. have looked at a lot of these controllers, and never caught that small difference in the prints. good post to learn from.
