Can anybody help me a bit here?

I need to figure out how many windings the primary and the secondairy have of TR2 of the Horvath schematics.

This is what i have for information:

Input primary: 300V by 22 amps

Output secondairy with a 100:1 ratio: 30kV and 220mA

Core is mild steel laminated

Frequency: 10khz

The drawing shows a 17 windings on the primary, but i dont know if these are the real windings count....

Hope someone can add some here....

Thanks!
