(Oops--should read magnetron)

Hello folks. My first post.

-Oven heats weakly--won't boil water on high
-Draws 300 watts on high (rated 1200 watts)
-Measures -10KV DC to case at Magnetron terminals on high (10 to 1 high-voltage divider measures 1KV on voltmeter)
-diode and capacitor appear to pass simple out of circuit tests
-magnetron did actually pass simple resistance tests

Looks like the magnetron is faulty?

Actually, I think my initial voltage measurements were inaccurate (too high) due to test equipment mismatch, but in any case the voltage is 50% higher than a working 400 watt oven.
