Ah, I used the wrong KCL around the transformers. After correction:

And with the correct values for Vi1 and 2:

The results now compare with those of ttokoro:

I get this:

Then:

On second view:

since both sources (Vi1 and Vi2) are DC, all voltages V1...V4 are 0 V, I2..I4 are 0 A and I1=24/7 A.

 

Success!

Based on the previous calculations, I get the following:

Your above one is right. I2=-I1/n. Therefore, if I1 is 1.265+0.586i, I2 should be 3.795+1.757i, instead of -3.795-1.757i.

So, your Kirchhoff's current law, KCL, is not correct. And n is not 1/3 but 3 for n1 and n2.
