Yesterday I checked again the oscillator coil and the primary (the one on the right in the sch) between pins 2 and 3 (the one saying 3.4 Ohm) was open.
It was a real pain to unwind it - so I tried to find some information and found a place where they say it is 13-14 turns and then two others where it is 17 turns. When I counted it I counted 18 turns by looking at the turns before unwinding it but then I doubted myself as I thought I counted some turns from the coil underneath (they overlap).

So today I think I will undo what I did yesterday and rewind it with 17 turns.
If anyone knows for a fact what the number of turns is, I could use some extra info.
