thanks Erik,
	As I am limited to 32 amps max on my power supply, 5 or 6  kva sounds
about. I did read somewhere (a long time ago) that you can measure the
magnetic property  of your laminations using a scope and a  hand wound coil
in some sort of bridge configuration. I seem to remember a figure between
0.7 and 1.2 being important?  Does anyone have any details on this. Is it
worth the trouble to find out or should I just go for an average. The
laminations are 0.5 mm ( 19 thou thick. )

thanks to everyone for the info on transformers. I will post details of my
design when I have read though all the stuff I have got so  far and come up
with a design.
