How could I forget Ampex? The station I’m at in Fort Myers, FL had a 3 M/E AVC Century from the early 1990’s until 2007, when we replaced it with a Snell Kahuna.
Ampex entered the switcher market when they bought Duca-Richardson in Colorado. The old ABC affiliate in this market had a Ampex 4100.
The “soap bubble” demo was a fun one to show off on the AVC. What an innovation to allow the modulators to control things other than just a pattern edge. It also had a great chromakeyer that rivalled a Ultimatte, called the SpectraKey.
In its later years, our Ampex AVC was dying a slow death. Some parts of the board just didn’t work any more. To its credit, it never kept a newscast from going on the air.
