Yes , 2 unbalanced x-formers is a bad thing.  I don't know how one would set
up both dimmers so they would always have the same resistance all the time.
I do however have some potentional suggestions.  The first would be to use a
small benchtop variac instead of the dimmers.  There are a few listed on
e-bay and are currently at a good price. You will need at minium a 10Amp
120V model.  Another idea would be to use a 1500W dimmer.  Grainger and
McMaster-Carr sells these if you are having trouble finding them, however
they are kind of expensive and are really ment for steady loads like a
lightbulb or fan.

I know this has been brought up before, so correct me if I am wrong in any
of my assumptions. I was originally going to use 1 1000W dimmer to control
two 60 ma 9kv NST's but apparently that probably won't work, so I will go
back to using 2 600W dimmers, 1 for each. My question is how to make the
dimmers at exactly the same position so that they are operating at the same
level. I have read that using mismatched transformers is lethal, so I am
assuming that having the two transformers set to different levels may cause
problems. Also for wiring purposes is there anything fancy I need to know?

Here's a link to the control circuit
