NE5532 manufactured by headphone amplifier circuit

NE5532 preamp generally used, performance is very good. Now used as a small power amplifier, how effective And the general op-amp circuit is almost the same, but one of the resistors, capacitors have a greater change, the state and not the same op-amp circuit.

Experiments show NE5532 for small power amplifier, excellent performance. In addition, the series with the input R1 (R6) 51K, because the volume when listening with headphones too, if you remove R1 (R6) can be accessed by five inches below the small horn, before documented, bedside listening was also very effective.
