This is the circuit diagram of video distribution amplifier. The circuit is use CA5100, 2N3053 and 2N4037 as the main active components.
Circuit operation is straight forward for amplifier circuits. The second channel for the audio amplifier is made up of the same components except the other half of IC1 is used. Pin 6 & 5 are inputs and 7 is the output.
