I recently built a 1:1:1 GDT and I scoped the output to see what the waveform looked like and I am getting some strange results. I'm driving the GDT with 12v and the scope reads 24V! that's average not including a little ripple. So my question is why am I getting 24v from a 1:1:1 GDT should it not be 12v? Also I did load one of the secondaries with a 470 ohm resistor this did not seem to change much. (also tryed 10ohm resistor, the resistor went up in smoke )

That's completly normal.
When you configure the UCCs like you did you formed a full bridge. You should research what a full bridge is, and analyze the circuit to figure out just why it does that.
