TDA2030 2x14W Audio Amplifier - DIY Kit

With this do-it-yourself kit based on the TDA2030 chip you can make your own amplifier!

Specifications:

• Voltage: 9-15VDC
• TDA2030 chip 
• Speaker impedance: 4 to 8 ohms
• Output power: 2x 14W (with 4 ohm speakers), 2x 9W (with 8 ohm speakers)
• Potentiometer present (for volume control)  
• 3.5mm female jack (audio input)
• Reverse polarity protection with a diode
• Cooling blocks for optimum cooling
• LED indicating the status of the amplifier (on/off)
• Components with values are shown on the PCB
• PCB format: 70x60mm

Note: At low voltages the LED will be less bright.

Contents of the kit:

• 1x PCB
• 4x 0.1uF (104) capacitor
• 2x 4.7uF capacitor
• 4x 47uF capacitor
• 3x 1000uF capacitor
• 2x 18 ohm resistor
• 3x 4.7k ohm resistor
• 8x 100k ohm resistor
• 1x 50k ohm potentiometer + knob
• 2x TDA2030
• 2x Heatsink + screw
• 1x 3mm LED
• 1x 1N4007 diode
• 1x 3.5mm female jack
• 3x Screw terminal

All locations of the components with value are listed on the PCB.  
Note: Instead of a 2200uF buffer capacitor a 1000uF capacitor is supplied. Solder this one to the location (C11) of the 2200uF capacitor.
