Quad 405-2 Power Amplifier - Fully Working The Quad 405-2 is one of the most respected British power amplifiers ever made, famous for Peter Walker’s “current dumping” (see below) amplifier design. It's a solid, compact unit with a heavy chassis (9 Kg), designed for durability and often used by broadcasters like the BBC. (The difference between the 405 and 405-2 is essentially that the 405-2 can better drive 4 ohm speakers as well as the usual 8 ohm.) Comes with Power Cable and Box. See photos for condition.
