Hi Jeff,
Just for reference, it was Mr Atwood who stated that the UBT1 was very marginal at ~510V and then only on condition that the secondary wasn't grounded and that the core was floated up to the voltage that the output stage was referenced to. He's the One Electron guy, so I take his word.
I'm sure there was probably some margin to his comment, and I guess it comes down to what you're comfortable with. In the end.. I'm happy with compromise.
