Case Studies of Famous Fixes.
Summary
Some of us have a fix we're especially proud of, or can think of one which nicely demonstrates a diagnostic principle, or which taught us something new. This is a page of "Famous Fixes" which hopefully will contain an ever growing collection of gems for our shared education and entertainment.

Mysterious kettle owned by the venue - we did not know the circumstances of the fault.
- Check the fuse (ok)
- Visual inspection (ok)
