An in depth look at analogue DC controllers focusing on the Gaugemaster model D and the Morley Vector Zero 2. Also how these model train controllers work. We try to find out why the GM produces such good slow speed control. I am not a technician, findings and views are my own. This is a long video with many technical discussions hopefully put in simple terms.
19thApril Hi again, I am pleased to say that today I have adapted the Morley to perform just as well as the Gaugemaster. This is done at the cost of maximum speed (just a little) as the output was higher. I am still finalizing components and then will consider making a 'how to video' but experience and understanding in transistor isolation, component identification and a means of testing capacitors to get a balanced pair will be essential.
Update re the GM, I spoke with the engineer who asked me to bring my controller in, he fixed the hum while I waited :) what great and open customer service.
I've removed ref to the disagreement Morley had with me as I think time has moved on and it's in the past now.
Final update: After extensive testing the adapted Morley is now my controller of choice. Having two independent transformers means no interference with each track channel. #modelrailways #modelrailroad #modeltrains
