The hybrid consists of three dice: the [[M080]] differential amplifier ("[[ft doubler|f<sub>t</sub> doubler]]"), and two D078 NPN output transistors in common-base configuration.
The hybrid consists of three dice on a [[BeO substrate]] − an [[M080]] differential amplifier ("[[ft doubler|f<sub>t</sub> doubler]]"), and two D078 NPN output transistors in common-base configuration.


It is the same as the [[155-0065-00]] (H074) except for the case and pin 3 to case breakdown.
It is the same as the [[155-0065-00]] (H074), except for the case stud and specified pin 3 to case breakdown voltage.
 
There is also an H074B ([[155-0125-00]]) version.


According to [http://hakanh.com/dl/docs/kitinstructions/050-1014-00.pdf Modification 050-1014-00, Vertical Output Microcircuit Replacement], the emitter resistors need to be selected according to a code printed on the device.
