As I noted in one of the previous postings here, at least one of them is an 
"A" model. This can be seen by the side panels, and somewhat by the RCA logos 
mounted on the front of the machine. 

My experience with TR 70's at NBC Burbank included the A, B, and C models. 
The A's were the oldest, RCA's answer to the VR 2000. The B models worked the 
best, especially in editing with the RCA programmers (edit controllers). The C 
models made the most amount of overtime for me, as they always had servo 
issues, especially with closed captioning edit sessions. If you had an edit session 
in bay 3 with the 70C's, you were guaranteed to run late.

Also in the Burbank tape room, one TR 70B was paired with a TCR 100. Every 
Tonight Show commercial (a program that, at one time, was responsible for 17% of 
the total network pretax revenue around 1980, so the story goes), was 
transferred from that 70B to that TCR 100. Needless to say, it was kept in top 
running shape!

Regarding TR 600s and 600A' there: There were 4 low serial # 600s paired with 
4 70As for zone delay. Only in extremely rare circumstances were the 600s 
ever placed on the air, and only for a few moments due to less quality from the 
600s. There was one edit bay (5) that had 4 TR 600As with a CMX 340. The 
prevailing thought was that the TR 600As never made picture as nice as the 70Bs. 

One of these days I am going to sketch out a floor plan of the NBC tape room 
before it was radically changed after the end of 2" days. I think it will make 
for interesting reading. It will be accompanied with photos.
