Quad 405 Power Amplifier (Second Hand)


Classic vintage Quad 405 stereo power amplifier delivers 100 watts per channel (8 ohm). This two channel amplifier is designed for domestic and professional use employing current dumping which eliminates many transistor problems. The Quad 405 can be used with the 33 control unit or similar high quality pre-amplifier. The high power output makes it suitable for use with many of today's high quality loudspeakers and provides opportunity for farther loudspeaker engineering development with less emphasis on efficiency.
