3,4 W power amplifier schematic

The schematic above is amplifier based on ic TA7211P or TA7212P , circuit above using OT transformer as a booster amplifier again. The amplifier suitable used on outside / field, because by using a transformer OT is identical to the PA amplifier.

Part List :
R  = 1K , 10R , 3K3
C  = 1uF , 10uF , 1n , 68u, 3u3, 2n2 x 2, 100u 
IC = TA 7211P / TA7212P

Technical information :
Max Vcc = 15 VDC
Min Vcc  = 4 VDC
Po            = 3,4 W
Rl            = 8 Ohm
Icco         = 16 mA
