connect pin8 of the opamp to 12v
and then adjust the gain with r8
to give a 0v to 12v output range

Re: 5V TO 12V (OFF TOPIC)
Thank you.
So I need to disconnect the 5V from pin8?
When saying R8...did you mean VR1 maybe?
R8 is a resistor I can't tune it, maybe change his value?
EDIT:
I looked at the schematics and only then realised that R8 is VR1
I forgot that your a schematics guy and not stripboard one.
My only last question is if I need to disconnect 5V from pin8?

yes
disconnect 5v from pin8 and then connect 12v instead
you already have a gain of 2
so that should allow 5v to get pretty close to 12v

Re: 5V TO 12V (OFF TOPIC)
I only attaned to get up to 6V - 7V maximum.
I just hope that I'll manage to get the x0x vco to that range.
Thank you very much for your help guest!
As always im more then gratful!
