Make a Simple Audio Amplifier

Step 8 Volume Controller

7-Now again join the 5th pin of the IC with the +ve side of 220 micro farad, the -ve side of the pin should be attached with the A of the 100 ohm variable resistor.The B pin of the variable resistor should be connected to the GND pin (4th pin of IC).This becomes the Volume controller.

does anyone know what voltage capacitors to install?

I'd choose 10v or higher. Just make sure it's higher than the 9v or it'll explode =D

as I understand, it just needs to be larger then the supply voltage.
