amplifier help

[pier1]

I made an audio amplifier using tba810 ang that is not working . The circuit only works when my hand is touched over the body of the mic . or on the body of the potentiometer .

Please suggest me a solution for this .

Hi Pier,
Attach your schematic with the mic and volume control wires shown.
Did you make the circuit in the datasheet?
Did you use an electret mic type? Is it powered correctly?
