ABSTRACT:
A color monitor includes R G and B gain blocks, in the form of balanced multipliers, and a potentiometer picture control for supplying a common DC gain control voltage to the differentially coupled transistor pairs in the gain blocks. A common black level control adjusts the zero level for the signals. Changes in gain control voltage do not affect black level or color balance of the picture tube display.
