This exhibit is a 6AU6 RF pentode for use up to 50 MHz and the Type designation contained within an etched octagon suggests an American maker. However, the only other identification is the series of letters GDX8.
The anode encloses the inner electrodes.
The thin glass tube envelope is 18 mm in diameter and excluding the B7G base pins the valve is 43 mm tall.
References: Data-sheet & 4054. Type 6AU6 was first introduced in 1946.
