Hi Finn,

The range is a manufacturing tolerance.  The full 900V gap fires 
repeatable to like 0.1%.  I imagine temperature does affect that 
though.  The SIDACs do tend to be very close to the 300V number 
though as far as firing voltage.

So they fire very close to 300V and they always fire at the same 
given voltage.  I can sneak the voltage up to a volt or two below the 
Vbo with no problem repeatably.  I remember one section fires at 927 
volts but I have not really paid any attention to the variation of Vbo.

Cheers,

        Terry
