Is this a quiz, or a question? Assuming the latter, here is the answer: The letters A and B were originally used to refer to the filament and plate supply batteries of a radio. In order to avoid confusion with these letters that referred to use rather than size, the letters A & B were omitted. -- Norm (strong@tc.fluke.com)
