Q6 is Motorola MJE6044 complementary Darlington output transistor、and Q7 is MJE6041 Q1 and Q2 are MD8002 dual transistor，Q3 is MPS-A56, Q4 is MPS-A13 and Q5 is MPSA06．For 8-ohm loudspeaker suppiv is ±36V with 6.2K for R4、430 ohms for R5、and 33K for R7.output center oltage must be maintained at 0 VDC to ensuremaximum signal swing and prevent DC voltage from acting on loudspeaker， Frequency responseis 10 Hz to 50 kHz for -1 dB points，Samecircuit is used with different components for other powers down to 15 W and for 4-ohm loudspeaker,-R G,Ruehs,″15 to 60 Watt Audio Amplifiers Using Complementan Darlington Output Transistors,″ Motorola、 Phoenix, AZ 1974, AN-483B, p 5.
