The 5651 is a small, special quality voltage stabiliser. The striking voltage is 115 Volts and the maintaining voltage is 86 Volts. For a tube current variation of 1.5 mA to 3.5 mA. The 5651 is essentially a voltage reference for use in a stabilised power supply.
The reverse is obscured by the internal coating.
The thin glass tube envelope is 18 mm in diameter and excluding the B7G base pins, is 46 mm long.
References: Datasheet Type 5651 was first introduced in 1948.
