Guitar amplifier schematic – used ICs: MC4558, TDA7294
Simple and very sensitive circuit. Can
be assembled easily on a perforated universal PWB. Keep all the input
leads very short in length to avoid input interference. Use high
quality shield wire to input signals. Easily available ICs are used.
The output IC TDA7294 should be mounted on aluminium extruded heat-sink, Use of heat-sink compound is a must.
Pin number 14 of TDA7294 is the audio output
In the given circuit diagram, the drawing is missed. Note it.
