I liked the detail in this story about the Raytheon 250 watt transmitter’s output being boosted with a homebrew linear amplifier. I looked up data on the 2000T tube, and it is one of those big bulb-shaped power triodes, possibly from the 1920s or 1930s. I suspect that most likely, the tube would have been used in a grounded-grid configuration.
