Hi there,
I've run some tests now.
Measured the output power with almost 5W at input voltage of about 9.1V into a dummy load.
I tested for continuity on all the coils. The soldering here seems to work fine.

I post some pictures of the test-screens...
Hopefully these pictures lead to the problem somehow
