If the resistance is different than the table indicates replace the transformer High Voltage Diodes The high voltage diode Figure 30 is assembled by connecting several 1000 1500 volt semi conductor diodes in a series to increase the reverse voltage capability In the circuit the high voltage diode conducts to prevent the filament voltage from becoming positive thus as the high voltage winding of the transformer goes to a peak of 2400 volts the high voltage capacitor is charged to 2400 volts gt 4 Figure 30 High voltage Diode When the high voltage winding starts to go toward negative the high voltage diode becomes non conducting with the charged high voltage capacitor in series with the high voltage winding When the transformer gets to its negative peak of 2400 volts the voltage applied to the filament is 4500 volts The high voltage diodes are rated at 16 kVDC NOTE The Single Mgnetron Sota uses only one diode High Voltage Transformers Primary Voltage Frequency Taps and Resistance Secondary Taps and Resistance 0 972 1 188 Q NGC 3062 1 208 VAC 60 Hz 1 amp 2 4 Ground 53 60 65 52 0 819 1 001 240 VAC 60 Hz 1 amp 3 0 972 1 188 NGC 3062 2 230 VAC 50 Hz 1 amp 2 3 Ground 57 52 70 30 Filament Transformers Primary Voltage Frequency Taps and Resistance Secondary Taps and Resistance 18 99 23 21 Q
