1V2

1.25V @ 0.2A Filament Drive Rail, 7,500V Peak Inverse Voltage (PIV), 0.5mA Max Continuous Forward Current, High-Voltage Half-Wave Rectifier Diode Vacuum Tube. It is engineered explicitly to operate as the high-voltage flyback retrace rectifier inside early color/monochrome television receivers and radar monitors, translating high-voltage alternating currents cleanly into stable DC anode potentials to safeguard geometric screen stability from distortion lines. Housed in a standard 9-pin miniature glass tube envelope layout with an top cap anode terminal connection. Exact part index: 1V2.
