[QuadList] History - what is the REAL story

[dcfwtx at aol.com]

A clairification to my posrting below:

"Heterodyne color all the way. 8:1 and LBC".
Meaning direct color recording. Aired (played back 1958-1965 +/-) in 
heterodyne (non-phased color mode) until direct color recovery 
available. Many of the shows from that time look superior now (when 
recovered and digitized) as compared to when they originally aired, due 
to advances in video head S/N specs., time base correction (direct 
color recovery, velocity correction), and dropout compensation. 
Additionally, network transmission (The Bell System), tube transmitters 
(video via AM modulation), and tube driven color receivers of early 
design, have been replaced with superior delivery and display 
equipment.

What were the networks playing back on in the late 1970's? Dennis Degan 
noted the four (?) VR 2000's at 30 Rock.
NBC Burbank zone delay was almost all TR 70 A-main, TR 600-backup, both 
HBC. CBS TV City (when I saw it) was VR 2000 HBC-main, VR 1000 
LBC-backup. The same for ABC Prospect. ABC replaced the 2" setup with 
early VPR-2's. CBS went with the BVH 1000's (I think). NBC Burbank had 
BVH 1000's and 1100's, then early production BVH 2000's. Does anyone 
here have any clarification as to who was playing back on what at that 
time (or earlier, other than the very first VR 1000's and TRT's)?

Here is the TRT-1AC rack layout from 1958. Note color rack # 6 in the
middle. 
 

It was this machine model in the beginning (later the TRT-1B etc.) that
recorded and played back NBC color shows such as: 

The Bell Telephone Hour, The Dinah Shore Chevy Show, The Andy Williams
Show, Fred Astaire, and on and on. Heterodyne color all the way. 8:1
and LBC.
