Hi Glyn and welcome. I found this thread from 7 years ago. https://www.routerforums.com/315775-post3.html According to Phil P it was the same router as a Freud FT 2000E router. We've seen a number of those that had issues with the speed controller. The problem if I remember correctly was an old style graphite wafer type potentiometer type speed control. The graphite could crack under the vibration present when routing. I'm sure there are no parts available. Collets were another issue and they are also non existent. Your only fix would be to bypass the speed controller. If you do much routing you should start getting prepared to purchase a newer router. Those ones were not well made. That's a voice of experience. I owned one.
