Hi, I was wondering if Hornby's HM2000 is suitable for N-gauge locomotives? I recently bought one off eBay and tried it with my N-gauge locomotives. They work all right but they seem to hum horribly, as opposed to when powered by a Bachmann controller.
I investigated the issue and found out that the problem might lie in half-wave rectification, and that hornby's power-clip contains a capacitor which should filter the power to the track. So I got hold of a hornby power-clip and soldered some wire to fit N power clips. This didn't seem to help much. If anything, perhaps a slight reduction of the hum.
Is there any solution to remove the hum, and above all, would using this controller damage my locos?
Regards.
