Re: usefull?

Hi Arwin,
             you can series two of them to make one center tapped 
transformer, but no more than 2.  To do this connect the bottom ends of their 
secondaries, the ends connected to the core, together.  Now wire their 
primaries up in anti-phase you will have a 17.5kV 700ma transformer running 
within its design insulation and power ratings.
At 12.25kW that is one bigggg psu, so what are you gonna build with it ?
