Hello,
It’s been a while since I’ve submitted a question. I have a few MTH power bricks with accompanying speed controllers. They probably came in starter sets bought around 2008. One by one the controllers have become quite erratic to where just a slight touch of the handle sends a few second surge of voltage to the track and the train goes racing. Is there any fix for this or are there any reliable controllers on the market that can be used with these bricks? I should add that I have or have had several other transformers so that these few have not had to do an abundant amount of work.
