John Laurence Linsley-Hood (9 February 1925 in Wandsworth, London – 11 March 2004 in Taunton, Somerset) was an English electronics engineer and designer of audio components.

He was educated at Reading School, , the Royal Technical College (Glasgow) and after World War Two, at Reading University. In 1942 Linsley-Hood joined the G.E.C. Research Laboratories at Wembley, working on magnetron development as junior member of a team. Joining the RAF aircrew in 1943, he was transferred to work on radar, then subsequently worked with T.R.E. (Malvern) overseas. After returning to university, Linsley-Hood joined the Windscale Research Laboratories of the Atomic Energy Authority. He was in charge of the electronics team in the Research Laboratories of British Cellophane Ltd. from 1954.^[1]

John Linsley-Hood is best remembered by hi-fi enthusiasts for his "Simple Class A Amplifier",^[2] which he developed to provide a good-quality performance comparable to that of the classic Williamson amplifier. The design was published in Wireless World in 1969 (April 1969 issue, p. 148), and later updated in 1996.

Linsley-Hood wrote for a number of magazines and published books on schematics for audio components, including:

• The Art of Linear Electronics (Oxford, Butterworth-Heinemann, 1993)
• Audio Electronics (Oxford, Newnes, 1995)
• Valve and Transistor Audio Amplifiers (Oxford, Newnes, 1997)
