the test result you have obtained, indicating a forward conduction with a
voltage drop of 7 volts measured across the diode, and reverse blocking with
9 volts measured across the diode, would suggest that the diode is good.

Thanks for that confirmation. Bummer. But now at least I know it's
most likely the magnetron.
