QThere is neccessity to decrease not the phase response till DC rangein order to increase the musicsignalresponse of extremely low frequencyrange. Therefore, amplifier is this employingno capacitors exceptonesfor phase compensation, and has an almostperfecttransient characteristics. OThe first stageFET(2SK97) a dual FETof even characterisis tics and has a large Cm and no-leakage currentat normal temparature. To avoid the influenceby temperature drift, such as center voltage(0V) deviation, this FETis used as differentialamplifier and operatesat cross point which is the optimum point of drain current(at about 3mA) against the temperature drift. QTransistors, TR05and TR07,the push-pull pre-driverstage functionsas currentdifferential amplifierthat the stabilized operationcan be obtained. In addition,the collector current of these transistors enough high to make linearity is excel lent. OSincethis Amplifier employsphaseadvancer circuits [C06, C08, C15, R29, C16 and R30J,which have not been frequently used,to compensate the phasecharacteristics on high frequencyrangeand is also made to have enough

3-1. Advantage

current on each stage to increase the through-rate, the performance on high frequency range is conspicuously improved. OTo avoid the voltage deviation, regulatedpower supply circuit composedof ZD0'1, ZD02 is employed.

3-2. Operation
The use of differentialamplificationat first stagedual FET, (FET01, FET02) and connectionof the FETto the differential amplifier composedof TR01,TR02,make possibleto obtain enoughgainand remarkable low distortion. The output signalsof TR0'1 and TR02are untiphase. The output signalof TR02addsto TR05,on the other hand, the output phaseof TRO1 invertedbyTR03,then,it becomes is input signalof TR04and TROZwhich cascoded are connection. The output signals TR05and TR07are inphase at that the operationof this stageis push-pulldrive and currentdifferential amplification.The power amplifierof the f inal stageis composed of SEPP (SingleEnded push-pull)symmetry comple mentaryin 3-stage darlingtonconnectiontype.
