I have read an awfull lot about gainclones but it seems an Article in AEM monthly in Australia is the one that predates everything on the web by at least 10 years, even dick smith kits that were just a steal of the AEM article the first ever published using the LM1875 on a 1" square PCB by the same guy that invented the DIGI-125. Rodger Harrison of AEM fame may know more about it. Does anyone know who came up with the first one that beats the 1985 article.
