Hi,
I did not understand if Alan meant that I can use the TL072CP or not or I have to buy another chips which are only TL072 and not CP.

I will open the Mono/Poly tomorrow and will see what I can do. Then I will let you know. If it is in a very complicated place I will not do it. If I am lucky enough and the chip is already plugged to a stand, I will replace it immediately :-)

Really, where is the pcb KLM-354 to my revision board (check the picture I linked on my first post).

Alan and Florian, I really appreciate your effort to help me.
