Measurement of high-voltage transformer AC high voltage output, then measuring the microwave tube FA end without DC high voltage. The high voltage capacitor pin on the element inserted lines all pulled down individually measured components, found that positive and negative resistance values for high voltage diodeWawservice manual download site
150k Ω (multimeter R * 10K block measurement of positive should be 150k Ω; with normal reverse should be infinite).Wawservice manual download site
