It has been 60 years but here goes!
Yes Jay, I too built a TRANSVISION receiver kit; also, later, the Heathkit color receiver. Both worked very well.
As for RADIO studios lets start at the top of 485 Madison. Somewhere on a high floor was Studio 1 which, when I was there, was devoted to Peter Goldmark and his sequential color work. Nobody I knew had access to this place.
Master control and TR11 (station breaks and net standby) were on the 21st floor. A pair of turntables were there for recorded commercials and in the event of a net failure.
The news studio 9 was on the 17th floor as was the newsroom and TR (transcription room) 14 where Joel Tall was the resident tech.
A good guy and inventor of the EDITALL editing block.
I was on duty one night when war was declared; Israel had invaded Egypt and all hell broke loose. When was this? 1956-7?? Dick Robinson the editor honcho on duty called up lines from EVERYWHERE . Jim Berry relieved me when he arrived next morning.
Studios 31/32 were local and on the 9th floor. Turntables and two 350 tape machines were there.
The 8th floor featured some (4/5 ?) tape rooms where in each two console Ampex machines were located with an announce booth. The tape operated at either 30 inches per second (!!!!!) or 15. We seldom if ever used 30.
Appros tape speed; the original AMPEX video recorders worked at both 15 ips and 7.5. We never used 7.5; the guard bands must have been non existent.
I am hard pressed but cannot recall where Studio 4 was; this is where I did "MUSIC THROUGH THE NIGHT", with Bob Hall. I did this one night a week; Joe Kulin was the regular man. Studio 4 was also where MORT GOLDBERG and I worked a New Years EVE Show.
21/22 in the studio building were for audience shows. My first job after indoctrination was Public Address in 21 for GRAND SLAM; with Irene Beasly.
AND so it goes. My first day with CBS was that day when the first Live (no tape yet) COLOR TV commercial show went out to America using the sequential system from Peter Goldmark. Several manufacturers had set up their prototype receivers in Studio 21 to demonstrate such. The pictures were gorgeous. This must have come from Studio 72 up on Broadway.
The sponsor was Longines Wittnauer; the announcer Frank Knight.
