Thanks,

Subject: [neonixie-l] Small variac needed
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,
