Marconi Mk VII Television Camera CCU type B3207
Bottom right are the four channel amplifiers, above are the pulse processing modules and the the left
the Field scan generator. The Line scan unit is in the camera head. Bottom left are monitoring, camera cable length and aperture correction.
To the right is one of the channel amplifiers showing two of the thick film modules, half way up the rear of the PCB.
As the CCU is heavy, it can be lightened for lifting by removing the modules.
