Hello Indonesia...
arick i think that this image would help you.
this is Diy PLL system with also transistor oscilator and show where is input and where
to conect output.
I hope that help....

I forget to tell you that i build one without PLL and work very very stable.
and yes you can change C7 to 5pF or better to 5.6pF
cheers

zlaatko thank's very much for your advice, I build it last night and works good....
later I will connect it with The PLL
maybe I will need your advice again

about the tx200, zlatko do you know how to improve the sound quality ?
