Product Description

6-10 Watt Stereo Amplifier Kit – K143

Kit 143 is a class AB 6-10 watt stereo amplifier kit designed for quality hi-fi applications using a TDA2005 module. It is easy to construct and has a minimum of external components. The module has output current protection and thermal protection. This is the data book circuit which produces an excellent sound. The supply voltage required for this kit is 8 – 18V DC at 1 to 2 Amps. Maximum output power will only be obtained with a power supply of at least 2A at 15V DC, and using 2 ohm speakers (or 2 by 4 ohm speakers in parallel). However approximately 4W per channel can be obtained with only a 15V DC, 1A supply into 4 ohm loads. The power supply should be well filtered to reduce mains hum, the on board capacitors alone are not adequate for this purpose but are necessary to ensure stability. Extra filtering is unnecessary if operating from a battery.

We spent a lot of time getting the tracks right on this single sided PCB to get the lowest possible THD. Getting the separate tracks to the earth pin is the secret.

Specifications:

  • L: 3″ W: 1-7/8″ H: 1″
  • Requires external 8-18 volt DC @ 2 Amps for Max Output
  • Frequency response : ~ 15 Hz to 50 kHz, –3 dB
  • Electronic Kit – soldering required

    :

    I have purchased a total of 5 of these kits. At first I got 2 of them, wired them up and tested them. Holy smoke these are terrific little amps. WHAT GOES IN TO THEM COMES OUT REAL CLEAN AND FAITHFUL, ONLY MUCH LOUDER, OF COURSE. Keep any signal handling ( preamping and tone control ) as dry and minimal as possible. It will probably
    only detract from the quality of the reproduced audio. Oops, I almost forgot to mention how easily they go together. ENJOY

    Great little amp. What goes in comes out CLEAN and CRISP. Started with 2, now I have 5. Try to keep any preamp and tone circuits simple and “dry” so as not to degrade the quality of input signal.
