K-line powerchief 120watt tranformer

I have 3 of these and I really like them they really deliver power for my size of railroading. Which maybe my problem. I regularly run 3 engines with one pulling a 8 coach lite combine. my 80watt lionel transformer wont touch it. Two of my three transformers have have the potentiometer burn out and now they out put a constant 18v. Has anyone else had this problem? Has anyone upgraded one of these.

The cases are pop rivitet together, I wasthinking about building a new case and installing a slide dimmer for the controller. Maybe I’ll but both of them in one case and have a duel 120watt transformer, I could even install a voltmeter and ampmeter. hmmm, may try this this weekend after the trainshow in louisville saturday.

This was a known problem with the PowerChief 120, you may want to Google around, but I think it is a bad connection or cold solder joint that can be fixed quite readily.
