One of the questions I am frequently asked is, "What does a gassy tube look like?"
Above is a good example. This is a gassy 224 tube under test. It has failed due to gas leaks.

Paper foil capacitors fail when the waxed paper between the foil
elements breaks down allowing DC voltage to “leak” between the foil
wraps.
