Howdy X:
I was the operator on duty that night when Bernie sent the engineers to raid the Raleigh plant. As I recall, the machines they removed were actually MCI reel decks. They were nice machines, as long as you kept the Molex connectors in the transports clean.
They left all the Scullys behind. Apparently they thought of them as junk. I was busy on the air and didn't notice they were taking out all the gear, until I walked into "Production C" to dub spots and saw the Scully sitting where the MCI used to be! I'm surprised they didn't go in the air studios when I was in the can to remove all the fancy ITC 99B cart decks.
They also took some expensive test gear, like a Delta impedance bridge among other items. As you said, all that stuff got dumped back on the loading dock in Raleigh after all the phone calls.
I recall that they removed an RCA backup transmitter from the 850 site. We never saw it again, so Bernie must have kept it.
