I discharged the High Voltage and did all the usual resistance
measurements on the magnetron, transformer and cap. I did remove the
diode and ran 10 volts in series with it and a 1.2K resistor. Got 3mA
forward and 0mA reverse current.


That sounds a bit low- I would swap the diode and see what happens.
(compare readings with the replacement first)

Let's employ Ohm's law. 3mA * 1.2kOhms = 3.6V drop. Diode
drop is thus 10V - 3.6V = 6.4V. Sounds just about right to
me for a typical HVR-1X type diode, which is apparently a
string of ten Si diodes inside.
