Hi Mads
Thank you very much for you valuable input – highly appreciated and just what I was looking for.
I will check on the super capacitor on the large PCB tomorrow and assess if it needs to be replaced.
For the X2 filter capacitors will this one work (given the distance between the legs is correct)?: https://www.elextra.dk/p/x2-st%c3%b8jkondensator-100nf-01uf-275vac-20mm/H22282
Again – thank you very much. (and in Danish: Tusind tak Mads!)
