Amateur Hall of Fame:

Constructor Converter Information
David Boynes First amateur to build a converter David built two convertors, none were sold to the general public
David Looser. Jim Daniels “The Pineapple” This unit was sold in numbers to the general public
Dave Grant, Mike Izycky “The Dinosaur” This unit was sold in numbers to the general public
Malcolm Everiss “The Domino”. This unit was sold in numbers to the general public
Darius (Converter designation unknown) Numbers unknown
Katharine Manton FOTH – PC hardware running Linux to do standards conversion.One-off though others have built their own now
Darryl Hock “The Aurora” By far the most prevalent converter sold thus far. I’m not sure but I believe 700+ now exist in the UK alone.


Note: If anyone can provide photos internal and external, build dates, technical info etc about the other convertors, I would dearly love to include them here to expand on each device in the “amateur hall of fame”.
