It's an 8v regulator.

As for the FET I have no clue what half the specs in the data sheet are but Vgs is +\- 20v and Vgs(th) is 2-4V. Is one of them the value I am looking for as they are the only two apart form the 500v Vds which is just the maximum voltage is it not?

Connecting the 10k on the irf9540 to the supply would turn it off as it is an p channel FET.
If it doesn't work hit it with a bigger hammer.
If it still doesn't work you probably shouldn't of hit it.
