Differences between Dumont and RCA cameras

Nore the camera control units for the Dumont cameras  (in the left photo) had two handles and a "Master Monitor" with a video switcher.
     (The RCA TK-10/30 camera control units had one handle.)

After the return of the Dumont cameras, and acquisition of the RCA TK-10/30s, we had to adapt to some lost capability:
We had to improvise a video switching device.
The small aluminum box, fastened to the transmitter control console, with cables attached at the rear was a crude push-button switch to change between cameras.
We had to adapt an old TV receiver for a "Master Monitor."
The box sitting on the console is an audio amplifier for the microphones.
Scott Elliot is the Director, using an old Military handset to communicate with the studio production crew. (Note the headset Bob DeBenedictis is using with the Dumont equipment.

Station Manager Dana Cox arranged for the loan of two Dumont image orthicon (I/O) cameras from Cincinnati ETV Station WCET in early 1966, and Leland Hubbell met the WCET personnel in
Dayton to pick them up. They are shown in the pictures of the TV Production class of 1966. Note that they usually were run with the side doors open, due to heat problems created by the large
 number of vacuum tubes in a small space. The camera cable connector was on the side, rather than underneath as most other similar cameras.

   The equipment WCET supplied consisted of the television cameras, camera control units, and power supplies, but not the syncronizing pulse generator unit.  Dumont used positive-going sync pulses,
rather than the standard negative sync, so an adapter was needed to tie the Dumont equipment into the WGSF system. A simple inverter was constructed in a surplus cabinet to interface the cameras
to the Sarkes Tarzian sync generator then used at WGSF.
The cameras were loaned with the possibility/option that WGSF would buy them.  The school district could not come up with enough money to make the purchase, so the cameras were returned
 to WCET in early autumn of 1966.
