I'm curious in these classes, MTH, or pervious lionel classes, what the level of training and/or prior knowledge would be. The mechanical stuff seems straight forward enough, perhaps complex in some cases, but I don't expect it to be particularly intense. On the electronic side, however, do they teach component level repair, or go for diagnosis of failure and board replacement? Also what level of skill would be the 'starting point' one should have before they went to such a class?
MTH identifies some standard components that can fail, but they do not go through detailed component level repairs, or deal with circuit board diagrams. All proprietary. From what I have heard same with Lionel. You diagnose down to which board, and if something obvious, you can repair, otherwise replace.
The level of detail I have gone too especially with the PS-1 and PS-2 boards comes from detailed backward engineering, tracing out systems, even removing a component to see it's effect. Plus a ton of circuit board repairs with symptoms I have figured out what failed and how to fix it.
I had basic electronic education decades ago, but no practical experience. Always good at logic problems, tinkering and repaired stuff since a kid. Stayed at a Holiday Inn while at MTH training, and now I am an expert. G
