What is the value of the high voltage from the transformer going into the magnetron so I can measure it with my HV meter? Oven wattage is 1100. Also, what method can I use to test the HV diode since most meters that have a diode test function can not test such diodes? I assume a HV diode is a diode that actually is several diodes in series in one unit and the average meter does not supply enough voltage to forward bias the diode?
