Gaugemaster DC controllers
« on: August 18, 2019, 04:31:01 PM »
 :helpneededsign:

I have a Gaugemaster dual controller (model D) for the up and down main lines on my layout which emits a low humming noise when switched on and is constant during the whole of the running period causing me some hearing discomfort. I also have a single Gaugemaster controler (Type 100M) for the MPD on said layout which is perfectly silent.  Any ideas out there ? :

Gugemaster offer a lifetime warranty 0 ll transformers hum ( a little) but if other components or case resonate, it may be audible.

turn it off, wait 1/2 hr for caps to discharge, unplug it and check mounting bolts inside / out. or send it to GM.

Do you have the two controllers mounted/located differently?

I have a 100M mounted in the middle of one of Coniston's baseboards (it's principally to provide the various output voltages I need, but can be switched to control some sections if required) and that hums fairly well - it's transformer hum. It doesn't bother me though.

You could try mounting/standing the Model D on rubber pads or some other vibration absorbing surface.

As said, all transformers hum. Some louder than others simply due to tolerances in manufacture and/or how they're mounted.

I have a multi-disc CD player in my HiFi rack that's really loud when sitting right next to the system, but unnoticeable from a couple more feet away. I might get round to popping the case and investigating the mounts one day, but for now it just sits on 4 felt feet to isolate it more from the cabinet and the other components  :D
