Dear Kees,

Thanks for the information. Well I am just the beginner for the electronics, I have some question.

As I compare your shematic and original, coupling capacitor is C17, am I right ? So first I have to remove it !
Then change R8(470K) to 220K.And also add all purple color caps and resistors to connect R14's leg.

Please also let me know, what will be the watt of the resistors ?

And the caps must be polar or non-polar ? correct ?

I just need your re-confirmation. This radio really works without problem and I really don't want to blow it
