Here is a select representation of documentation that viewers will find helpful. 

The manuals provided here are primarily in English, but I have the also provided German, Italian, and French versions of various select models.  If you have a need for a version not listed here, please send me an email through the Contact the Curator widget (yellow widget) on the right side of the page. I will let you know by reply email if it is available or not.

May I commend Lectroneers 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.
