Documentation in acrobat format

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. Kit includes the TDA7294 IC. 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.

Dual Unregulated Power Supply (kit)

designed for our CPS106 audio power
amplifier. It is also suitable for any power
amplifier module or circuit requiring a
positive and negative rail voltage of up to
45 Volts per side. The output voltage and
current will depend on the transformer
chosen, and this is not supplied with the
kit. Never use a transformer larger than
35V-0-35V, as the capacitors voltage
rating will be exceeded. (CPS186)

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.
