Documentation in acrobat format (K68)

This is a basic adjustable voltage power supply using the popular three pin regulator, LM317T. You can select any voltage between 1.5V and 30V using a potentiometer. The LM317T is rated at 1.5A so you must use a larger heat sink when drawing high currents. Unregulated AC or DC input via terminal block or power jack. Requires a suitable transformer.(CPS68)

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.
