The posting by 73 de Ray jogged my memory a little bit.
He is correct about the Studio 53 or "Swing Control Room" in BC.
The east side studio definitely was the old Monroe Theater on 1st Ave and 76th St. I agree that it was a hard place to get to from PABT. Lucky for me in that CBS paid my cab fares. I also remember all the good restaurants in the area.
For some reason, even though I worked on that Project for about a year, the Studio # does not register in my old brain but I will accept the St 52 designation.
I'm pretty sure that ATWT was the only tenant of that Studio. When I first saw the Monroe Theater it still was configured as a Theater with a stage, an orchestra and a rising mezzanine seating area. As I previosly said, I was the Project Manager for the Electronics design and Installation. Facilities Engineering was involved in the extensive building renovations. The Stage and Orchestra areas were made into one level to provide a level Studio Floor area. The rising Mezzanine area was converted into an open two level control room. The lower level contained the monitor wall and the upper level level the Production Console.. The Audio Control Room used one of the old Audio Consoles that was formerly in one of the BC Studios. The Production Area was equiped with a new video switcher (cannot remember the manufacturer but I know it was a Canadian Company). The video area was similar to the BC video areas but as I recall all of the video equipment was housed in a row of equipment racks directly behind the video operators position. A new lighting console was also installed to the right of the Video area.
It sure gets tough remembering all these details from the past.
Dressing rooms and offices were costructed in the prior entry area.
