4 transistor amplifier circuit

4 transistor amplifier circuit diagram:

This is a 4-transistor amplifier circuit diagram. here used 2sc5200 and 2sa1943. this board can make 250 watts. we can use 25-0-25 voltage to 70-0-70 voltage. we have to use dual voltage positive negative and ground voltage. here we can get the component list to make these circuits.

R1+R2+R3+R4=0.22/5w. R6+R16=1k/0.25w. R5=10k. R7+R9=3k3/2w. R10+R13=20k/0.25w. R11+R12=330/0.25w. R8=100/3w. R14=220/2w. R15=36k/0.25w. T1=C2073. T2=A940. P1=224/250v. P2+P3+P4=100nf. P5+P6=56pf. P7=334. P8=181. Z1+Z2=12volt.C1+C2=100uf/100v.  Ic=TL071.
