Thanks for the responses. I am taking my transformers to a friend who is electrically inclined and can solder well sometime this week. Meanwhile I bought rail pliers for the 027 section to crimp the rails correctly around the pins. I have checked polarity on the 027 section and they are all correct.
I purchased some more lockons for the O gauge section and am in the process of installing them, which I hope to complete today. Will test every couple of connectors with my new-to-me transformer, so I don't fry another one. The O gauge track is in much better condition than the 027 from 1957.
BTW, is anyone on the forum near me? I'm in Sparks, NV.
