Before I purchase a new magnitron I checked with an ohm meter as follows:
red ohm meter lead to red magnitron lead and black ohm meter lead to black magnitron lead....result about 1/2 ohm,
black ohm meter lead to red magnitron lead and red ohm meter lead to black magnitrton lead....result about i/2 ohm.
Both magnitron leads black then red to ground.... reading infinite ohms (no needle movement).
Do you still suggest a new magnitron?
