Ok in the image of the schematic has 100nF i read and they said that is also 
0.1µF or is it 0.10µF and also the 220nF is it 0.22µF i just want to clarify that if is true.
And the potentiometer is it a 22K...

The other question i have could this be power with two 9V battery. 
Well thank you..

Yes the caps are all the same value

100nF = .1uF = 0.10uF

220nF = 0.22uF

 

There is no pot in that circuit

 

cheers

The capacitor values are the same.

 

uF (micro farads) is 10 to the negative 6th power.

nF (nano farads) is 10 to the negative 9th power.

And yes, you could power that circuit from a pair of 9 volt batteries.

THANK YOU SO MUCH TOO.... some people being telling me that i wont be able to use two 9V and that i need a beefier PSU... but other tell me that i could use two 9V but it wont sound that good and battery will die fast....

Thanks again.............
