How many of you have been halted on a restoration project because you couldn't decode the colored bands on resistors or the colored dot patterns on capacitors? That #47 dial lamp really seems dim -- isn't there a brighter one? What is that burned-out VT-24 tube -- is there any commercial tube that would substitute for it? Some of those formulas would be a lot easier to calculate if you knew the conversion from meters to feet or Celsius to Farenhite.
