My immediate impression is the poor drive to Q5, using a darlington configuration is a very poor idea, drastically reducing drive voltage and current. Reconfiguring the circuit with Q4 as PNP would be a big improvement.
I'm also not very convinced by the use of a single ended class A output stage, which will be very inefficient and get very hot.
Does your simulation allow you to calculate the dissipation in Q5?.
Yes I can view the dissipation.
I am running it high for maximum current output.
I am not very good at amps, I did have trouble with it up to this point. For 30 watts in I am getting 130 watts out. What would you suggest to amplify the osc?

I don't understand how you can consider that R8 and C8 can be considered to behave like a spark gap. Can you explain ?
I was wandering how you worked out that 30 KV at 4 mA was 130 watts. I think that should be 120 Watts. You have not given any details of the load. As you have not shown any details of the load I wondered if you considered the 200 meg resistor (R8) to be the load. But with 30 Kv across it it only dissipates 4.6 watts.
I agree Nigel that you can't get more power out than you put in.
One small point I didn't mention is, you need to take the average over a integral number of signal periods for the best accuracy.
Thus, if the signal period is 1ms, the integration period must be multiples 1ms.
