The KTZ73 is an RF tetrode for RF and IF applications. It was part of the M-OV 'Uniwatt' range of valves for use with mains or vehicle lead acid batteries.
A year later in 1938 the valve became the KTZ73/6J7G RF pentode. The main differences were the heater being standardised at 6.3 Volts and making it a pentode with g3 connected to pin 5.
The classic envelope is 29 mm in diameter and, excluding the IO base pins, is 72 mm tall.
References: 1043 & 3002. Type KTZ73 was first introduced in 1937.
