Marconi MkVIII Television Camera extender and geometery corrector PCB

Marconi MkVIII Television Camera A & B differences

The extender PCB was fitted in slot 10 in the A version, the B version had the geometry corrector card in that position. Note the metal tab on the corner of the 1A10 PCB that prevented the removal of the camera PSU until 1A10 had been removed.


There were a number of other changes to accomodate Light Bias tubes, extended red tubes, geometry presets in the CCU, highlight overload protection (h.o.p. or a.c.t.) and lots of small changes in the light of operational use. Detailed in handbook suppliment vol.5

The special Marconi Allen Key tool at the top is use when ajusting the mecanical postion of the scanning yokes.
