The Original TK-45

Wed Apr 19 22:58:21 CDT 2017

You are correct. The elusive TK-45 of 1954

One did exist in Boston at WGBH as late as 1983, but reportedly was sent to a Springfield PBS station for telecine use. The project foundered and the camera system was discarded.  Sad end to be sure. I did see it working as a telecine camera at WGBH in 1966-1967. Worked as well as a TK-26 on a film island. Sad loss.

The Museum of the broadcast television cameras  has a good list of RCA Cameras at http://tvcameramuseum.org/rca/rca_list.htm  by my experience they are a missing one camera type, that is the original TK 44  a three Vidicoin color camera designed for use in operating rooms, 10 were produced for medical use. to my knowledge only 3 were sold the rest were given away. I know it well as I worked with it at the Army Medical Center in 1956-7 and at the University of Michigan in 1958-62. Later while at RCA I sold the TK-44A  (Plumbicons) after an abortive attempt by RCA Lancaster to provide a modified 3 " IO to compete with the Philips Plumbicon Camera.

Paul, Where will you be located.  I spent 22 years with RCA (61-83) and never came across a TK34.

Oh yes. With two RCA cameras, hopefully working.

DARN!  sorry to miss this...

I did  see Paul Beck and crew last year though and enjoyed seeing the old  gear and actually meeting Paul in person at last.

Is  Paul's  crew also  going  this  year to  demo stuff?

Subject: ATSC 3.0  station taking shape for NAB/Image Orthicon cameras returning

Thought you'd want to know that the ATSC 3.0 demonstration station is taking shape on Black Mountain in Las Vegas.

One of the people helping to build the station is QuadList member John Turner, head honcho at Turner Engineering in New Jersey.

He advised the Old VTR's group this morning:

"We are building a real time ATSC 3.0 transmission system on ch 50 at Black Mountain for the convention. Pulling this RF off air at the Grand Lobby and North Hall. Big demo will be a 65” LG OLED consumer receiver being sold in Korea today.

Content is UHD stored on a Harmonic (Omneon) 50TB, 2 RU server. The server is playing out digital video at 8X 1080I!
Sure interesting to compare this new system to the 1960’s analog VTRs.

John (My 50th consecutive NAB this year)"

Turner helped build the ATSC 3.0 station at NAB last year, and has participated in a number of other NAB demonstration projects over the last several decades.

He also enjoys restoring Quad and other vintage video tape equipment in his company's New Jersey facility.

The "NextGen TV" demo area is in the Grand Lobby  between North and Central halls.

More about the ATSC 3.0 demo here:
http://atsc.org/news-release/next-gen-tv-hub-showcase-benefits-new-broadcast-tv-standard-2017-nab-show/#.WO-pPjxHaEc

"Tomorrow's technology" is just a short walk away from where the Museum of Broadcast Technology is bringing a showcase of vintage television gear to the entrance of Northhall opposite the taxi drop off.

In the last several years, the Museum's exhibit has showcased 2" quad video recorders along with a number of portable television cameras from the mid to late 70s and early 80s.

MBT's Paul Beck advises this year's display is RCA:  "One original TK-31 with tubed power supply and one TK-34 with WP-16 and external focus regulator. And... an original ZOOMAR 3x1 studio lens.

Yep !  (Image) Orthicons are making a come back !!! You just wait and see !!!!"

Should be an interesting NAB, that's for sure!

I'll have an announcement about the "Annual Quad Videotape Group Luncheon at NAB" in a forthcoming separate email.

As always it will be on 12:30 PM, Tuesday, April 25, 2017. The location is being identified. It will likely be near the MBT exhibit.

Looking forward to seeing folks there. Unless something changes dramatically in the next two weeks, we will be walking the floor rather than standing in a booth.
