'54 CONRAC monitor

Does anybody have one? I have tried to imagine what would have become of those. For example: I expect there should have been at least ten units delivered to the RCA building in NY in time for the first broadcasts. They probably were used into the '70's. Then I expect they were moved to a ground level place to be picked up by some TV/electronics company that tries to resell them? Maybe some ended up in a below ground level storage? I just don't think they immediatlely crushed them. I often wonder if buildings like that have a completely known inventory or if stuff, big and small, becomes forgotten for many years.
Does Anybody know about this sort of thing?
Did any of you ever work in the RCA building?

I'm not sure about the RCA building,I guess you are thinking about NBC
television studios at Rockerfeller Plaza.Since I work for CBS I can tell you
that back in '54 they used modified RCA CT-100's as color monitors.Then
they stepped up to 21" Conrac roundie monitors that used the 21AXP22
crt.In the 60's they started using rectangular crt Conracs which were a
hybrid design.I have one of these in my collection and even though it is a
hybrid,it is still a monster with 2 6080's as pass elements in the power supply.
CBS in their infinite wisdom threw all that stuff out during the 1980's,
including hundreds of Mcintosh and Marantz tube hi-fi,fairchild compressors,
Neumann U77 and RCA ribbon microphones,and other things that if I mention
I will make myself sick.I started working there in 2003.They also had alot
of stuff over in the transmitter room at the Empire State Building,But it was
cleaned out and the contents dumpsterized after the 9/11 attacks.CBS
started using Sony and Ikegami monitors in the 80's and have stayed with
those brands ever since.

Swanson

RCA had a 15 inch monitor in 1954, the TM-10. At least one survives. We have a GE and a Dage 15 inch in our collection:

Burbank used home sets

It appears from this magazine cover that NBC Burbank used consumer sets (RCA of course) - can anyone identify what chassis/model these are, and what CRT?

CBS New York must have been special. I've seen Television City shows from the late '70s (at least as late as '78) where they were still using round Conrac monitors.

The roundies were long gone by the 70's at CBS NY.At that time they were
using Conrac RHA series transistor color monitors.These monitors had a
separate HV power supply and two flybacks,one for horiz. sweep and the
other for HV.If the horiz. or vert. sweep failed the HV supply would
shut down to prevent the crt from being burned.CBS NY still had quite a few
of the Conrac CYA (hybrid) rectangular color monitors still in use up untill
the early 80's.

Those are a trio of RCA Victor 21-CT-55 consumer color sets with a 21AXP22 picture tube.

I worked at NBC Burbank in the 60's off & on. The RCA 21" professional monitors were in use in the control rooms. The studios had something like CTC-10 table model sets hanging above the audience section in some studios. Working at KTLA-TV full time in the late 60's, I was about 5 minutes to late to claim a 15" color monitor when they cleaned out their equipment storage locker. They had 3 sitting in the parking lot up for grabs.

picture of a tech. adjusting a Conrac color roundie in studio 72.This is my
first time attaching pictures.Hopefully I won't goof it up too bad.

"CBS" CT-100 monitor

Click to a picture of the CBS transmitter room in New York City, 1955. I believe ths is the pix Swanson's referring to in the previous post. The sole color reference monitor is an RCA CT-100 receiver, on a wheeled dolly, seen to the left of the operator.

Steve,

I know we've talked about this before but was I astounded in 1974 or so when I used to bluff my way into NBC Color City, Burbank and to my surprise saw really old (even then) 21" roundies used as monitors, etc. I mean, heck, not even rectangle tubes? Round? Wow. There was a guy in master control (you know, the room with the glass window so you could look through in the long hallway by the news entrance?) and this guy was adjusting one of the two 21" sets right there. I remember (burned into my brain) that one of the sets was marked "program" and one was marked "transmitter". The transmitter picture (after the signal came back down the mountain) was somewhat degraded when compared to the first picture, but both looked, um, antique compared to any modern TV set picture of that year. I couldn't believe they were making picture judgements and adjustments using those old sets as gospel. Heh, just floored me.

I mean, I love the picture on my old roundies but I wouldn't use them in professional video work.

That would be like in my line of work mastering music for CD's while listening critically to playback on an old JBL horn or something. It sure wouldn't tell me the truth about what was happening.

I could understand tv stations or maybe ABC using roundies into the 70s but it would sure seem that RCA would make sure NBC always got the latest & the greatest. Maybe there use of those old sets says something about their quality-and about the quality of what RCA was producing in the 70s!

I could swear I have seen studio shots on tv from the early 80s, either SNL or the Tonight Show, & they had Japanese-Sony, I think-monitors. I would think this would set Sarnoff spinning in his grave! This was before the GE buyout, by the way.

Tv stations or broadcasting facilities will quite often hold onto old equipment and run it into the ground because management does not want to spend
money on new equipment.There are certain areas where you need the
latest modern equipment,such as cameras and the color monitors that
are needed to set up or "chip" the cameras.These are the areas where you
will find modern equipment.In less critical areas of the facility you will find
the older equipment still chugging along.We still have alot of the Conrac
SNA series B&W monitors running.These are a transistor design going back
to 1974.No one makes crt's for these anymore,so we send out the old ones
to Scotty at Hawkeye to have them rebuilt.The plan is to eventually replace
all of these with Sony or Ikegami LCD monitors,but that will cost money.
It is rumored that yearly bonuses given to CBS management will be bigger if they spend minimal money.So of course they are going to do anything they
can to hardly spend any money.I'm sure this is how it is at other big
companies too.
Regards,
Swanson

I agree. Those old monitors were there at NBC because they still worked and they were "fixed assets" that were paid for 14 years before.

I STILL THINK I've seen COLOR CRTs from the 1950s that were the same shape as the B&W CRTs of the day-NOT the distinctive "Roundie" shape we all know & love. And I believe I've seen 'em as studio monitors-pictures, OK, but still. They may have been superimposed, but I don't believe they were. Am I dreaming, or Nutz ? -Sandy G.
