Thisamplifier uses a dual 20 Volt powersupply and delivers 15 watts RMS into an 8 ohm load. Q1operates in common emitter, the input signal beingpassed to the bias chain conSISting of Q8, Q9, D6, D13 and D14. Q8 and Q9 providea conSTant current through the bias chain tominimize distortion, the output stage formed by a discrete darlingtonpaIR (Q2,Q4) and (Q7,Q11). The last twotransistors are power Transitors, specifically the 2N3055 and MJ2955.The 7.02K resistor, R16 was made using a seriescombination of a 4.7K, 680 Ohms, and two 820 Ohms. The 1.1Kresistor, R3 was made using a 100 Ohms and a 1K resistor. You canuse this circuit with any walkman or CD player since itis designed to take a standard 500mv RMS signal.
