Stereo Preamplifier - Tone Control Unit
 
This is a preamplifier and tone control unit
which will make a useful addition to any
of our power amplifier kits. It is extremely
easy to construct due to the use of a special IC,
the Philips TDA 1524A. This contains all the
circuitry required to provide up to 20 dB of
voltage gain, +/-15 dB of bass and treble
control, channel balance, and a switchable
loudness contour.

Touch/Contact Switch
 
Both types of switches are built onto the one PCB so you can see and explore how each type works. A battery can power the touch switch (2 contacts) but a power supply (like CPS4) must be used for the touch plate (1 terminal) to work. High quality 12V relay rated at switching 240V/3A supplied. Uses 14011 IC. (CPS10)

50W amplifier module TDA7294
 
The heart of this amplifier module is a monolithic integrated circuit from SGS-Thomson, TDA7294. It is intended for use as an audio class AB amplifier in hi-fi applications. It has a wide voltage range and output current capability, enabling it to supply the highest power into both 4 Ohm and 8 Ohm loads. With the addition of a handful of parts and a suitable power supply, this module will deliver > 50W RMS into 8 Ohm @ 0.1% THD. HEATSINK NOT INCLUDED. User must supply a heatsink rated at 1.4 deg C/W.
