Early Electronic Television
ATC VK-5 Kinet
The Kinet was designed as a "slave" receiver, connected to a master receiver which had the majority of the electronic components. The Kinet has only 4 tubes: two 4 pin 879s, one 57, and one 5 pin with no markings. One of the uses for the Kinet was to be in department stores, where several were to be installed to advertise products.
One magazine article mentions that the set has a 9 inch CRT. However, measurments from a surviving set indicate that the tube had to be about 7 inches in diameter. It had an 8 pin base. Here are photos of the only know surviving set:
