How to make a pocket headphone amp!

In this instructable, I will be showing you how to make a  headphone amp. If you have some big headphones such as Sennheiser, beats by dre or some other big headphones (in my case, some sony MDR-XD100) an or an MP3 player isn't enough, especially if they have a high impedance. This circuit was originally  developed by a man by the name of and it has been extremely popular. There is only one difference with mine (and most others) and that is the fact that he used two single op-amps and we will be using a dual op amp.
So lets get started!



Please don't be too critical, I'm only 14!

Step 1 Parts

Here are the parts you will need:
OPA2134PA op-amp. There are alternatives but I have had most success with this one. The only other one that I would recommend is  OPA2132
1x IC socket
2X 470uf or higher 10V capacitors
2x stereo audio jacks
2x 0.2uf MKT or pollyester capacitors
2X Pannel mount LEDs
1X NPN transistor
1 or 2 9V battery clips
male header pins
1X PCB
1X stereo 10k potentiometer
10k, 100k, 1k, 4.7k, 47ohm resistors (I got packs of 8)
2x SPDT micro switches
3v button cell and holder

A PROJECT ENCLOSURE! Be creative!

It's a 10kohm dual log potentiometer (generic) found at my local electronics store.
