Hi Terry,

- I *assumed* the diodes to block the *free* exchange of energy, 
which is a precondition for resonant rise. Obviously I need to have a 
look into my text books again.

65 H and 162,5 nF resonate at 50 Hz which is exactly the local 
frequency of the mains. I should measure the inductance of the 
secondary winding of this MOT also.

Are there any means of protecting the secondary winding of the MOT? 
Spark gap?

- Is the factor always "three times"?

- It was not potted.
