Re: [TCML] MOT Measurements

[bartb <bartb@xxxxxxxxxxxxxxxx>]

Hi Ted,

Not that high. Terry's MOT measured 65H at L2. My own MOT measured 39.5H 
(although my MOT is a bit beefy compared). I would expect Herwigs MOT to 
be no lower than 20H. Your calculated value of 4.7uH is extremely low. 
How are you basing this value? Herwig is 230V 50Hz power environment. 
Are you assuming a 120V 60Hz situation?

Take care,
Bart
