The National Union Jan-CNU-6V6GT/G 6V6GT/G Glass Nos. 1943 4700/4800 mho is a vacuum tube that was originally manufactured by the National Union Electric Co. for use in various electronic applications, particularly in radio and early television technology.

This vacuum tube is a pentode, which means it has five active components in its electronic structure.

The tube's glass enclosure is cylindrical in shape and measures approximately 3.2 inches in length and 1.1 inches in diameter. It has a metal base with three metal pins that serve as the heater, grid, and plate connections. The tube requires a warm-up period before it can be used, which is typically around 10 minutes.

It was also used in early audio equipment, such as vacuum tube amplifiers for hi-fi systems.
