[Elecraft] [K1] TX part sick

Hi all,

I am trying to repair the son's K1 where the TX seems to be sick. (receiver
sounds hot and quite nice on both bands 40/20m)

I found several C0G caps around the cores on the module board burned as same
as K1 relay so I replaced them all after long time searching them on the
market (EU). 

Now I am trying to check step by step according to manual the RF board (RF
2000 Rev.D) and I found that original builder (we did not built it) wound 5
turns of secondary T3 (green wire) instead of 4 described in manual. 

Should I remove the turn from T3 or is it possible to adjust the TX even
with that mistake?
I would like to avoid another burns...

Many thanks,
