1974 JVC GC-4800U two-tube portable color camera

This was JVC's first color video camera. As you can see, it was owned by "Sight in Sound", which was an electronics store that sold mostly audio equipment like stereos, record players, records, cassette decks, etc. in the 70s 80s and 90s. The logo is hand painted onto the camera on both sides.

The camera has a 4X zoom lens and a 1.5 inch electronic viewfinder. It has a separate CCU which weighs only 3 pounds, and has an EIAJ plug for powering from a power supply, or the mating PV-4800U VTR. A record button is on the front of the camera. This camera uses two tubes, one mounted horizontally, and one mounted vertically. The horizontal tube is the chrominance (red/green/blue) tube, and the vertical tube is the luminance (black & white) tube. The camera head contains the deflection/power boards and the CCU contains the color matrix circuits and the sync encoder. The two tubes in the camera produce the raw color signals, and these signals are sent to the CCU. The CCU takes this "pre-video" and matrixes the color into one signal, which is then encoded to a composite NTSC video signal. The CCU also provides sync to the camera. 

The matching VTR for this camera is the JVC PV-4800U 1/2 inch EIAJ-1 color VTR. This was the only reel to reel, portable color VTR of the time, that did not require a special power adapter to playback in color. The CCU is packed into the carrying bag for the PV-4800U VTR.
