Here is a select representation of documentation that viewers will find helpful.
The manuals here are in English, but I have the German, Italian, and French versions available if needed. Just send me an email through the Contact the Curator widget (yellow widget) on the right side of the page.
May I commend the visitor to examine the presentation on the disposition of the Lectron System which began in 1971? It is quite a story and shows how thorough Braun’s analysis was for marketing, sales, and consumer consumption. I have had the original German document translated into English on an alternative page by page basis. German and English speaking visitors can enjoy reading this unique bit of Lectron System history!
Some of the manuals are quite large in size and will need to be explicitly downloaded through the link as the Google preview function has a self-imposed file size limit.
These links go to my Google Drive account.
