I guess I already found the problem. On the primary side there are a 1u
50V and a 47u 25V capacitor, both 85°C. Thomas said I should replace
them with > 100°C, even if they look ok.
I've got capacitors on stock, but bad equipment for soldering. Unsolder
already was hard, but I can't get it soldered, especially since the 47u
I've got, has got a larger diameter, since it's a 35V. Reading glasses
btw. are less good for soldering, I need to find a better tool to see
when soldering. Thomas has got some special glasses.

Thomas has got Hameg oscilloscopes with component testers.

Btw. the capacitors I unsoldered are broken now, even if they should
have been ok before. Not because of heat, but to take hold of the
capacitors damaged them.

Thank you Gene, Thomas tries to visit me in some hours.
