Gentlemen,
Where may I find an alignment procedure for this radio chassis?
Thanks,

Mario and Carlos,
I downloaded a service manual from Radiotechniek and yes it is in Dutch. I think I can manage through the alignment since there are plenty of similar looking words.
I may come back to this board to ask help with certain sections. I usually have difficulty with FM alignments just after the ~10.7 MHz IF steps.
Looking at the section for the UL41 tube function is interesting too.
I find the cross cultural/language differences quite challenging, intriguing and enriching.
Paul.
