The Koyo "Parrot" is of Japanese manufacture, has the full compliment of 4 subminiature tubes. In spite of it's tiny size, it's a standard super-het circuit! It's also the smallest of the subminiature tube radios, so small you would think it's a transistor radio. Battery requirement: 1-45 volt "B" battery, 1-1.5 volt "A" battery. It measures 5X3.5X1.25" and weighs just 15 oz without batteries.
