The G180/2G is a 150 Volt cold cathode voltage stabiliser with a regulation of 5 Volts for currents between 5 and 45 mA. This version is fitted with flying leads rather than the B8B base pins.
The 180 refers to the striking voltage.
The G180/2M is electrically identical but has pins in the B8B base cap.
The cathode cylinder with central rod anode.
The B8B base with the pins replaced by flexible leads for direct soldering into the circuit.
The wide glass tube envelope is 29 mm in diameter and, excluding the B8B base pins, is 62 mm tall.
