Hi Malcolm,

Do you have any detail of your experience like.

1. Where were the enormous voltages and how high do you estimate they were??
2. Did you have any terminations in your cable?? series resistance at 
the SG end, or RC to ground termination at the transformer end??
3. What kind of transformer died??
4. What do you think the mechanism was??
