Replacing Power-Cord Resistance Elements or Ballast Tubes

Have an old radio that used power-cord resistance elements or ballast tubes that are no longer available? Ed Lyon has taken Charlie Rhodes' equations for determining how to replace those with modern-day capacitors and created some charts to guide your repairs. Published in the September 2017 Radio Age, they are provided here for your use.
