Sorry for taking time to get back to this thread, have had a week on the road with only time for brief glances at the board.
I?ve emailed a link to Shaun for this conversation and he plans to contact David Rees early next week to discover what circuitry info he is comfortable discussing.
David is a quite unique in that he has been designing circuitry for in excess of 5 decades now. He has never been one to seek the limelight, lives in a remote part of Wales and has never had an internet-connection; as a result we believe David?s designs to be very pure, and it would simply not be cricket to divulge any information without his full approval.
BTW, Shaun is up to his eyeballs prototyping new products at the moment and has asked me to convey his Best regards to Monsieur Purpose :guinness:
