I am in the process of bypassing the speed control module on my PC 7518 and wiring in my own speed control. Amazon has several options but all have some bad reviews. I suspect many of these reviews are people trying to speed regulate soft start or speed controlled devices. Some have stated the device worked then simply failed. As with many tech reviews on Amazon, I noticed the majority of negative comments due to quality were within the past few years. Not unlike the people who have had their 7518s for years and can't fathom that PC now makes substandard power tools.
Question: Has anyone found a more robust speed regulator? Perhaps a unit designed for industrial applications?
