[…] The headphone output of the amp will really serve only high impedance headphones somewhere in the realm between 250 to or even up to 600 ohms. Most headphones used with audio devices such as phones are around 32 to 50 ohms. I would not recommended used them in this circuit unless adding some transistors to the output stage. […]

In reply to Nandhakumar. I know that this is an old query but 28 turns of wire around a 1 cm core of wood, aluminium, cord etc, but NOT iron or similar metal, to give a coil around 5.16cm long, will give you and inductor of around 6 micro-henrys. I hope this helps
