Plenty of sets used a 12AU7 video output, including the Raytheon/Belmont I've been working on. RC 19 lists it specifically for that application at 2.75 Watts plate dissipation. It's interesting how GE chose the 12KP4 in 1957. They must have felt is was a more robust tube than the others available, or possibly they were sitting on a big stock pile of them.
