NOT:
-Devre şemasında sadece sol çıkışı görmektesiniz.
-R3 'ün degeri kulaklık oldugu için 300 ohm olarak degerlendirildi ve 68K kullanıldı, eger 600 ohm yada daha fazlasını isterseniz R3 degerini 100K yapın.
*Total harmonic distortion @ 1KHz & 10KHz: Below 0.05% on 32 to 600 Ohm load and up to 1.5V peak-to-peak output. Below 0.1% at maximum output
*Frequency response: Flat from 30Hz to 20KHz
*Sensitivity: 90mV RMS input for 2V peak-to-peak output
*Output voltage: Above 2V peak-to-peak on all loads
