The Marconi MkV camera is completely
solid state apart from the EHT rectifiers, stabilizers and the Image
Orthicon camera tube. The 7" tilting viewfinder, B3128, is used
on the MkV, MkVI, MkVII, and with some modifications on the MkVIII and
MkIX cameras. It has a high brightness of 2150 lumens and can resolve
over 600 lines. It has proved to be reliable in service considering
they are all at least 30+ years old now. Some of the early CRTs have
a defect with the tube faceplate bonding. This leads to spots on between
the tube and the front glass. |
