5.000 W ultra-light, high-power amplifier
This circuit is of an 2x 2,500W RMS stereo amplifier, super-light and
without switching-mode power supply. The circuit just shows a channel, and the
power supply that it assists to the two channels. The audio circuit should be
duplicated, but the power supply assists to the two channels without problems.
A special care should be destined to the insulating transformer of the
audio line, that should be of audio-high-quality, of the type used in microphone
pre amps input line. The whole group (2 channels) of 5,000W RMS it should not
weigh more than 32 lbs, already inside of an appropriate metallic box.
Warning
This circuit is exclusively for amateur use. It contains not-isolated
parts of the electric AC net and it can be very dangerous. The connections for
the speakers are not isolated of the domestic AC net and it requests extra
care. This procedure seeks to substitute a conventional power supply with great
weight and cost reduction, without necessarily to use a switching-mode power
supply.
This procedure cannot be allowed in some countries for commercial-use.
The author doesn't have any responsibility for the form as that circuit it will
be applied.
