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.
