Help to transfer the voltage ml 360s

[Mark levinson]

Hans seems to have figured out the secret of this board. In order to convert to 240 V, you need to connect 4-5.
Judging by the black mark on the pad, the tension should be under it and looking at you.

I find it hard to understand your pictures but connecting 4 to 7 is the safest connection available because all windings are in series.
When the secondary voltage turns out to be too low, you could connect 4 to 5, skipping the winding 1 to 2 of T1 and increasing the secondary voltage.
But I doubt very much that 4 to 5 is for 240Volt, I definitely think 4 to 7 is correct.
