Hi folks,
I tried the HV setup I wrote about a couple of days ago, and naturally,
it does not work, because the transformers I use are designed for 230V
primary voltage, so they are saturated at around 270V and cannot be used
to obtain 380V AC as planned originally.
However, I now plan to use a variac (230V, 1.6A) and a 230V <-> 400V
transformer (20VA) in series, providing me with up to 400V AC when I
connect the 500V transformer backwards. This is no problem because it is
designed for this voltage.
But the variac - with its 1.6 amps - is still a little too powerful for
my taste. Does anyone of you guys know where to get a small one with
20VA or so?
The smallest I could find is this one here:

Thanks,
