Kitronik High Power Amp Kit (PCB & Components)

This amplifier kit can output up to 15W per channel into a pair of high quality speakers. The kit is capable of producing a very loud, high quality stereo sound. The product includes all the components required to build the PCB, but not a power supply, speakers or cable to connect it to audio equipment.

It features a power LED, on / off switch and volume control.

This kit includes:

• 1 x Printed circuit board
• 1 x TDA7297 audio amplifier IC
• 1 x Heat sink
• 1 x M3 nut and bolt
• 1 x 10Kohm dual potentiometer
• 2 x 47Kohm resistors
• 1 x 1Kohm resistor
• 1 x 1N5400 diode
• 1 x Blue LED
• 1 x 470uF capacitor, electrolytic
• 1 x 10uF capacitor, electrolytic 
• 1 x 100nF capacitor, ceramic disc 
• 2 x 220nF capacitor, ceramic disc
• 1 x Right angle PCB mounting power switch (high current)
• 3 x Two way terminal blocks
• 1 x Panel mounting DC power socket

PCB dimensions: 77.5mm x 59mm. Four mounting points are available, one in each corner.

This kit requires soldering.
