  The present invention provides means for controlling the electron
guns of a color type cathode ray tube having the usual video and color
circuitry, wherein the grids of the electron guns are controlled by a
variable oscillator which may be responsive to the sonic or audio
output of a sonic or audio generator or record player or other audio
source.

  The oscillator may be a variable chroma oscillator, or the
oscillator may be a variable RF oscillator, the output of which is
adapted to be mixed with the signal from a fixed frequency color
oscillator.
