Tomas,
You could use the 5Kv transformer with a voltage doubler for 10Kv DC at
500ma. This combine with an ASRSG would make for a very nice power
supply.

Hi Tomas,
Yes you can connect the two 5KW transformers together providing:
1. The secondary of each in not center tapped grounded.
2. If each transformer only has one bushing, you dont need to worry
about forming a center tap between the two transformers. If two
bushings are available, you will need to ground one of them.
3. You phase the primaries correctly so one transformer puts out a
negative voltage when the other transformer puts out a positive voltage.
I recommend that you DON'T USE these high power transformers until
you gain more experience. These power levels can be deadly. Use the
4.5KV NST for your first coil.
