Zener Diode 9.1V 10W tested Power Grid Bias Amplifier Ham

Description

Unused NOS 9.1V & 10W Power Zener Diode KZ705, a clone of 1N2973.
I test every diode to make sure it works.
This diode can replace the grid bias 50W zener in a Dentron MLA2500. KZ705 handles about 1 Amp of plate current, use them in parallel to get more.
Features:
Nominal Zener voltage: 8 - 10.2 V
Maximum Zener Impedance: < 2 Ω
Low leakage current
High reliability - military surplus (see the military marking)
Mechanical data:
Case: see the picture below
Polarity: see the picture below
