[BC] DuMont TV Camera

[Chuck Conrad]

I know this is basically a radio forum, but since the topics has drifted into TV recently, I thought I'd consult you folks, since you may know where the bodies are burried.  Some of you may know that I'm restoring a 1949 TV mobile unit that was built by DuMont Labs for Channel 8 in Dallas. 
 
I've found some of the parts of a DuMont TA-124 camera that actually belonged to Channel 8.  It may have even been used on theTelecruiser.  Among the missing items are camera cables and their connectors.  DuMont had a proprietary connector they used for everything.  I'm probably going to have to fabricate something, but it would be nice to have the right parts.  You can see a picture of the male connector at www.telecruiser.com It is on the top of the home page, so it will be hard to miss.
 
If you ever see any of these, please let me know.  And now, back to our regular programming....

Since on my netbook the default "printer" is a PDF converter, I have PDFs of the final "here's what you sent" screen. I'll paper-print those and file in the public file(s) soon.

Why would you need to place them in the Public File?  It's not an application or a pending proceeding or action before the FCC.

Go to a remote, set up the excessively heavy gear and then
and then and then, it wasn't tall thin Jones. But soon as you
got a signal back and clock was perhaps 2 or 3 minutes to air
somebody would flick the breakers at the wall, the truck goes dark,
and you have to wait for tubes to warm up,and set up the cameras
again. This was black and white, and you still had to set shading etc.
Blow a slide projector lamp or the auto lamp changeover had a blown
spare bulb in the film projectors. That's cause "somebody" didn't replace
the main and you were on the spare not knowing it. All this without film splices
etc failures. More in the next one.

Tube failures in the motor drive units to the videotape
deck. Remember, the motor drives for capstan and head
were just simply audio amps that spun the motors locked to
either vertical sync freq 60 or 59.94 Hz or 15,750/15,734 Hz.
Lose a drive pulse, such as blanking or horizontal/vertical
pulse and watch the IO tubes burn a trace quickly. Such fun.
More later.
