OK - condensator - you are right
Near to C9103 there is C9117 with " R 33k 1kvk 9298"
I think this is 33pF.
Could it be also 33pF for C9103? Can I try with 100pF or 150pF or 300pF? Is there no difference for the function for MOSFET (C9103 is placed between Drain an Source)?
What do you recommend? I have to order new one, so there is no difference for me.
Thanks again to all.
