My Motorola 9VT1 ran for years on the original metal ballast. One day I was watching it and it just turned off as though someone pulled the plug. The ballast tube just burned out. I replaced it with a glass one and no problems since. They do last but run hot and can go bad. I like electrostatic sets. They work well and are an interesting part of early TV history.
