RCA Vidicon Camera
RCA's first vidicon camera system from 1950. On left is the camera and lens, on right is the camera control unit (CCU). The camera body contains only the vidicon tube, two stages of video gain, and deflection coils (pictures below), all other voltages and signals are supplied from the CCU, which is typical of broadcast camera systems.
the original tripod, the system is complete, although it is
not functional presently as there is a loss of B+ somewhere
in the CCU, after the rectifiers. Tracing wires is a
nightmare as all the wires are tightly laced and color coded
wire is almost non-existent, also there is a power resistor
on the lower deck that is disconnected and I cannot tell
where it should be connected or if it is even needed, and
lastly there is an empty socket on the main chassis that I
have no idea what was connected to it. Really need a
6326 vidicon tube
Inside components of the camera. Construction appears all hand made. The vidicon tube presently in the unit is a 6326 which I am sure is not what was originally in the unit. Originally it used an RCA 6198 tube, the first production vidicon. The 6198 was designed for studio applications, the 6326 was for use in film chains. Another clue is in the present tube connections, the 6198 has 4 grids using 3 connections, grids G3 & G4 are internally connected to pin 6. The 6326 has 5 grids using 4 connections, grids G4 & G5 are internally connected to pin 6. The vidicon socket is wired for only 3 grid connections and an external wire is used to connect the extra grid of the 6326.
You can find additional information on the early vidicon tube here.
You can see a very early Philco vidicon camera here.
|This side view shows the timing chain that develops the sync frequencies. The master oscillator runs at 31.5KHz, then divides down for the 15,750 Hz horizontal and 60 Hz vertical frequencies.|
This side view shows the video amplifier. This appears to be more of a production unit than the camera construction. It may have been a production CCU for an IO camera that was modified to work with the vidicon camera.
Rear of the camera unit, the connector is the same large size that was used on the 40's & 50's vintage IO cameras. The large connections are coaxial and carry the video and sync signals between the camera and CCU. The CCU has an ID plate identifying it as a Model 1; Serial Number 504. Other than the RCA "meatball" logo there are no identifying markings on the camera unit.
