| Historical research into electron tube manufacturers, mainly in the Netherlands, by Peter den Boer † RIP 2025-02-23
| | From the end of last century to around 2025 Peter den Boer did a lot of research to old Tubes and their manufacturers. Also he has a very nice tube collection. Peter has everything in A4 Binders (Band in Dutch) and it's good that he also scanned everything so we can easy access all his work in digital files. Pity that everything is in Dutch but with google translate it is not difficult to translate interesting parts. The total file size is quite large: about 60GB. There are a lot of double files... The structure is a little bit trashy. However it contains a lot of interesting data that can be preserved this way for people interested in this material. (2024-10-12)
