Why no love for this GE roundie ?

Check your last work. If you mounted a cap backwards, mixed up caps, or have a short or base wiring mix up all of that could cause what you describe. I've burned open power resistors on a can restuff, and all I did wrong was confuse which terminals were which (causing a polarity reversal).

If all you did since it last worked was that can, then it should be easy to fix if you pause, and look at it with fresh eyes.

Learning to find your own mistakes is an important part of your growth as a restorer...When you see your own mistakes you will subsequently make less of them.
