Default Re: Cooper Smith Amplifier

Hi, there were a number of Cooper -Smith designs, if you have no luck with the site you could try Radio Constructor mag. This used to publish the Cooper-Smith circuits.
If you are based at the Wickham in NE England I'm not far away and may be able to find the details.
