Working on a ge microwave. It does every but heat. The high voltage diode
tests open in both directions with my meter. I've never tested one of these
puppies before. Can I assume it tests just like an ordinary diode?

From the sound I'd say the hi voltage transformer is working. Windings
check out ok with meter as well as the filament in the tube seems ok.
Getting about 85 ohms from the filament connections to the metal case of the
tube. That's another one I'm clueless about, don't know if that's good or
bad?

Thanks in advance for any advice. I've got some regular electronics
experience but never fooled around with a microwave before.
