FiftyFourA Posted January 6, 2015 Share Posted January 6, 2015 I have fitted DCC (non sound) to my O gauge steam locos but now I have a Heljan Class 31 and I would like any helpful advice on fitting DCC with sound. Stuff like how many speakers & where to fit them; what to do with the fan circuit board; will I need resistors for the lamps etc. I dont think I need 'stay alive' capacitors with the pick-ups and weight of a Heljan loco. Of yes, nearly forgot, any views on Zimo chips vs Loksound. Link to post Share on other sites More sharing options...
