About

I am a "Full Member" of the AES.

From 2000 onwards I have specialised in record reproduction with an emphasis on pitch stability and wow and flutter. My work has been mentioned on numerous occasions in newsstand magazines all over the World.

Latterly I have been working on early 78rpm records of both lateral and vertical modulation. I designed for my company the only precise control system in the World for accurately setting the speed of a turntable from 10-150rpm. This DDS device has 0.01rpm resolution and is measurabley accurate to 10ppm in the real world.

I have now (2014) finished working on an "Owl 1" "Owl Multifilter" and "Vadlyd MD12 MK3" replacement for analogue real-time equalisation of all 78's. The new TE-01EQ is now in use by leading archiving and restoration institutions including the New York Public Library and Indiana University Bloomington both who were so impressed they ordered a second one each.

In November and December 2013 in the newsstand magazine HiFi World, I had a 4 pages 'feature article' published about the philosophy of direct drive turntables.

In 2015 I did some research on why mono cartridges sound better on mono records than stereo cartridges used as mono.

2016 is the start of even more archiving and restoration projects including a cylinder reproducer using modern technology and in the long term an affordable modern accurate cylinder player.

______________________________

I first started in Audio in the late 60's as design engineer for Marriott Magnetics, where to customers' specification, I designed and specified magnetic recording heads which were used in applications from high quality audio to ticket readers for the London Underground.

Later as the UK took to the concept of a "Music Centre", I oversaw the manufacture of 18,000 FM Stereo tuner boards a year at RMS Audio in Cavendish for the LoFi industry where RF was too difficult.

In the 80's I was a senior design engineer for Philips Electronics in Cambridge and was solely responsible for the transmit audio processor and FM audio demodulator on the PF85 and PFX hand help radio telephone as used by the police and others throughout the world. The production run ran unaltered to over 250,000 units.

In the 90's I specialised in radio threshold extension and audio processing of the audio telemetry channels of the NOAA weather satellites. I have given 7 lectures in the USA to NOAA and NASA scientists on the audio signal processing of their satellites and also the usage of the satellites by Universities and Third World Countries. The latest lecture was April 2013.

Non-AES Awards & Award Nominations

In 2013 presented with an award by the United States Department of Commerce for "29 years of service to users of weather satellites".

2014 my restoration and archival turntable won the UK "Turntable Of The Year" award.
