GE Color Film Chain
I know that WNAC-TV in Boston (An RKO station) had GE PE-24 cameras on their film chains around 1968 or so. As I recall there were three film chains that used RCA projectors and one that used Eastman 285's. The RCA chains also had a black and white RCA vidicon camera, so you could select either color or B&W to put on the air, depending on program content.

RKO's other major GE order, in 1966, was for a huge bank of PE-250 color cameras, the lion's share of which went to WOR-TV (six for use at Shea Stadium for Mets broadcasts, three for their studios), others went to WNAC (five, I.I.N.M.) and WHBQ (two). No, in terms of film chains, apart from WCBS and the GE PE-240's that were shared with CBS network at the vast Broadcast Center, New York was otherwise generally RCA territory from the mid-'60's and into the '80's.

Hi all-
In an earlier post, I mentioned that the Museum of Broadcast Technology (Woonsocket, RI) would be receiving a GE PE-240 color film camera shortly. Sure enough, last week a shipment arrived with the GE in good cosmetic condition, but when the top access door was opened, it was completely absent yokes, tubes, and optics! Plus the dreaded encoder .Groan. Still, some observations can be made about this camera. First, the build quality is excellent. As with RCA, GE Electronics Park was a defense contarctor, so the wiring and layout were of top quality. The optical bedplate had to be 5/8"-3/4" thick aluminum. There were test points on one card for masking (color matrix), suggesting a variable matrix-something not available on the TK-27. Also, there was reference to the GE "AutoTrast", unless this was a module also used in the live camera. This was an auto knee circuit that became common on Japanese and European ENG cameras. But, there was a muffin fan on the ear of the upper housing, and from photos seen of the GE 4V design, the deflection assemblies and optics were not enclosed, as in the RCA designs. If so, I bet dust was a serious problem. If anyone has the missiing pieces to a PE-240, please contact off list-TK41C@aol.com. Regards, JB |

To bring this back to life, it appears CBS's first GE color film chains would have been the PE-24 class - as they delivered their first 4-V color chain to the network's Broadcast Center in New York per this link to a Broadcasting magazine article in its April 26, 1965 issue when their line was the PE-24 (and about a year before they developed the PE-240 - the first references to which were in a GE ad in the March 21, 1966 Broadcasting):
https://www.worldradiohistory.com/hd...%20electric%22 I was right, though, about both BC and Television City using GE chains. But Broadcasting has also been illuminating in other ways. A July 18, 1966 article noted that while WCBS-TV, having access to network facilities, was already loaded for color, WCAU-TV ordered RCA TK-42 cameras; WBBM-TV, KMOX-TV and KNXT all ordered Marconi Mark VII's - and all four would receive or had received RCA TK-27 film chains: https://www.worldradiohistory.com/hd...rca%20tk-27%22 (p. 54) https://www.worldradiohistory.com/hd...t%20marconi%22 (p. 55) Last edited by W.B.; 11-04-2023 at 05:28 AM. |

WCAU had not just TK-42s but was pretty much full turnkey RCA in the late '60s - surprising for a CBS O&O. RCA Broadcast News from June 1969. Story starts pg. 24:
https://www.worldradiohistory.com/AR...ws/RCA-142.pdf (And elsewhere in that issue is the wrapup from the 1969 NAB show that highlights the new TK-44A cameras and TCR-100 "cart" carousel some of you may be well familiar with.)
