Homepage of Bertie Genade

I am an electronics engineer who have started my own business, Gentronics, a little over ten years ago. I have a Masters degree in electronic engineering, which I have obtained at the University of Stellenbosch. I am based near Cape Town in the Western Cape, South Africa. The companies I am doing contract work for includes the Medical Faculty of the University of Stellenbosch, the University of the Western Cape, Gabriel S.A, Blue Cube, Cinegate  and Table Mountain Motion Picture Studios.

I design and build or upgrade equipment in the fields of audio, video, laboratory equipment and industrial electronics. Examples of these can be found on this webpage. I also do repairs of laboratory equipment including waterbaths, sentrifuges, stills and power supplies. I also do repairs of older audio equipment.
