Hornby Controller versus Gaugemaster Controller (ELIMINATE THE BUZZ!!!)

Picking a controller for your Model Railway isn't always a choice, as you may only have the one that came with a starter set. But if you do choose to upgrade to Hornby, Gaugemaster, or any other model railway controller manufacturer... choose wisely! If you are hearing a "buzz" from your locomotive, it is likely the controller, and I can show you how to eliminate that!
