I have a Marklin HO 3 rail layout that I built when I lived in France. It has a 6002 (230v) power supply to a 6021 didgital controller. I have just tried to run it here in the UK bit it has problems. The digital side of it doesn't work and when I run a non digital 3 rail train it will only go backwards and without and speed control. I know there was a UK power supply 6003 at 240v but I'm not sure whether the malfunction is just a 6002 v 6003 issue or whether the controller is malfunctioning. Can any one tell em if the problems I'm experiencing is just the 230v issue. Also does any one know if there is a later version of the 6003 transformer as it appears not to be available.
