From October 1964 through to April 1975 I was working with Clive Sinclair at Sinclair Radionics: these were the early days when Sinclair was into audio amplifiers ad kits. I worked on a number of the earlier audio designs, before I went into management - I ran the service department.

As a consequence, I have an amount if information on the Sinclair designs, which I could write up and add to the member's area if there is interest. There's significant amount of work doing this, hence the members are!

The products I can supply information for are:
