I have troubleshot this thing as far as I know how. Here is what I know...

1. I have 120v into the high voltage xfmr
2. Output of HV xfmr is unknown as I cant test high voltage with my meter
3. Capacitor checks good at 1.05 uF
4. Diode checks good, and replaced with new
5. Magnatron test good ... shorted across leads and not shorted to gnd
6. Output of HV transformer Ohms good per tech data sheet.
7. Checked all connections and wires are good

As far as I can tell this Microwave should be making serious heat, but it will not even heat the smallest amount of water.

Any suggestions would be greatly appreciated. So far I am leaning towards the HV xfmr. But directions on other things to check would be helpful.

PS all other functions of the microwave work IE the controls, timer , turntable etc.. work.

Thanks in advance. Rufus
