AUDIO AMPLIFIER KITS
"The Champ" Audio Amplifier
KC-5152 $6.00 plus postage & packing
This tiny module uses the LM386 audio IC, and will
deliver 0.5W into 8 ohms from a 9 volt supply making it
ideal for all those basic audio projects. It features variable
gain, will happily run from 4-12VDC and is smaller than a
9 volt battery, allowing it to fit into
the tightest of spaces.
50 Watt Amplifier Module
KC-5150 $22.00 plus postage & packing
This 50 watt unit uses a single chip module
and provides 50WRMS 8 ohms with very
low distortion. PC Board and
electronic components supplied. PC
Board size only 84 x 58mm. Requires
heatsink. See website for full specs.
• Heatsink to suit HH-8590 $12.50
Universal Stereo Preamplifier
KC-5159 $12.50 plus postage & packing
Based around the low noise LM833 dual op-amp IC, this
preamp is designed for use with a magnetic cartridge,
cassette deck or dynamic microphone. The performance of
this design is far better than most preamps in many stereo
amplifiers, making it a worthy replacement if your current
preamp falls short of expectation. It features RIAA/IEC
equalization, and is supplied with all components to build
either the phono, tape or microphone version.
• Measuring only 80x78x30mm, it is ideal for
incorporating into existing equipment
and is hence supplied short form of PCB
and specified components plus PCB
standoffs for mounting.
• +/- 15VDC required, use KC-5038 $11.00.
• If power is not available in your equipment
use MM-2007 $5.50.
KC-5495 $32.75 plus postage & packing
An ideal project for anyone wanting a compact and
portable stereo amp where 12V power is available. No
mains voltages, so it's safe as a beginner's first amp.
Performance is excellent with 20WRMS per channel at
14.4V into 4 ohms and THD of less than
0.03%. Shortform kit only.
• Kit includes PCB & on-board
• Recommended heatsink
Cat No. HH-8570 $4.50
HIGH PERFORMANCE 12V
• PCB and all electronic
"Pre-Champ" Versatile Preamplifier
KC-5166 $6.50 plus postage & packing
This tiny preamp was specifically designed to be used with
the 'Champ' amplifier KC-5152. Unless you have a signal of
sufficient amplitude the 'Champ' will not produce its
maximum power output. The 'Pre-Champ' is the answer
with a gain in excess of 40dB, which is more than enough
for most applications. You can vary the gain by changing a
resistor and there is even provision on the PCB for an
electret microphone. Use AM-4010 $2.00.
CLIFFORD THE CRICKET
KC-5178 $12.50 plus postage & packing
Clifford is created on a small PCB, measuring just 40 x
35mm and has cute little LED insect eyes that flash as it
sings. Just like a real cricket, it waits a few seconds after
darkness until it begins chirping, and stops instantly when
a light comes back on.
• PCB, piezo buzzer, LDR plus all electronic
• Power requirement 6-12VDC.
THE SUPER EAR
KIT OF THE MONTH
Hearing Loop Receiver Kit
KC-5497 $22.00 plus postage & packing
A hearing loop is an inductive assisted listening
system for the hearing impaired. They're typically
installed in venues such as churches and conference
rooms to enable listeners to receive in-ear
communication via a wireless induction loop. You can
now install this technology on your own TV, home
theatre or hi-fi system. This will enable someone
who's hard of hearing to hear at their own volume
level without having to turn the volume up to a level
too high for everyone else. The receiver will drive a
pair of headphone or earbuds from the
signal picked up from the hearing
loop. The whole unit is completely
self-contained and can be carried
around in a pocket or you can add
your own belt clip, so the user isn't
constrained by a set of headphone
leads. The kit is complete with case,
• Current consumption: 10mA
• Frequency response: 100Hz - 5kHz
• S/N ratio: 67dB
Battery voltage indication: Down to 7V
KC-5469 $20.25 plus
postage & packing
Enables you to run a stereo amplifier in
'Bridged Mode' to effectively double the power available
to drive a single speaker. There are no modifications
required on the amplifier and the signal processing is
done by this clever kit. Supplied with silk screened PCB
and components. Requires balanced (+/-) power supply.
• PCB: 103 x 85mm
BRIDGE MODE ADAPTOR
FOR STEREO AMPLIFIER
KA-1809 $20.25 plus postage & packing
Assists people who have difficulty hearing high audio
frequencies, or use as an interesting education aid in the
classroom. By amplifying high audio frequencies,
conversations will be made clearer and you will hear
sounds not normally heard such as insects or a
watch ticking. Kit supplied with case,
processed panels, PCB, 9V battery,
and all electronic components.
• PCB: 56 x 26mm
Note: Not a replacement for a proper hearing aid.
"MINIVOX" VOICE OPERATED RELAY
KC-5172 $12.00 plus postage & packing
Voice operated relays are used for 'hands free' radio
communications and some PA applications etc. Instead of
pushing a button, this device is
activated by the sound of a voice.
This tiny kit fits in the tightest
spaces and has almost no turn-on
delay. 12VDC 35mA required. Kit
is supplied with PCB, electret mic,
and all specified components.
• PCB: 47 x 44mm
KG-9092 $9.50 plus postage & packing
This kit generates a deep sounding noise similar
to fog horns on ships. Use as a unique warning
siren or to improve a child’s toy. Operating
voltage is 4.5V to 12VDC. Output power up
to 5 watts depending on the input voltage
used. Requires an 8 ohm speaker.
