tda7293 rear small board
diy kit need yourself weld
Technical parameters: Output Power: Maximum power without distortion 250W . Speaker Impedance: 4-8 ohm impedance speakers can be connected. PCB size: 40MM * 116MM * 1.6 double-sided sheet KB Supply voltage: DC dual 18V-50V, recommended dual 35V (note not double 35V transformer, is plus or minus 35V DC, recommended dual 26V/200W These toroidal transformer, rectified DC voltage of about dual 35V) reminder: TDA7293 high voltage when the sound is much better than the low voltage.
Material Introduction:
1. All resistors are 1% precision metal film resistors, capacitors for Nippon, rubycon and other fever capacitor polarity P hilip s CBB, 3.3uF AUDIOPHILER MKPcapacitors! 2. new import TDA7293 amplifier IC!Three TDA7293 30MM hole spacing Product pictures:
PCBboard silkscreen with component values are very convenient DIY 
3Pin is DC power input terminals: -VCC GND +VCC select Dual 18-50V AC voltage.
recommended dual 35V
Right side environmental green 2Pin 5mm is input terminals: GND IN , Audio input connection 
2Pin 5mm terminal is output terminal, OUT GND Directly to the speaker
