This vintage tube and tube socket from Valvo is the 6922/E88CC edition. It provides an easy and affordable option for replacement part needs on a radio or television set or can be purchased as a vintage collector's item. The tube socket functions like an electrical socket into which vacuum tubes or valves are plugged. It holds the valve in place and provides terminals, which can be soldered into the circuit, for each of the pins. Sockets are designed to allow tubes to be plugged in only one orientation. They were used in all electronic equipment to allow tubes, which failed relatively frequently, to be quickly tested and replaced.
