Sinclair Audio Circuits

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 most is likely to be in the members area!

The products I can supply information for are:
