Hello. I have taken a standard old 1kva microwave transformer and removed both coils. I want a 24v centre tapped primary and a 50v secondary and rated for about 500va. Can anyone please tell me the best gauge wire to use and the turns ratio? Any help would be truly appreciated. I hope its as simple as that. If not, well, thats ok...

Is it a steel core unit? What are the physical dimensions?
