| Historical research into electron tube manufacturers, mainly in the Netherlands, by Peter den Boer †
| From about 2000 upto 2024 Peter den Boer did a lot of research to electron tubes and their manufacturers. Also he had a very nice tube collection. Peter kept his work in A4 binders (band in Dutch) and it's good that he also scanned everything so we have easy access. 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: over 60GB. There are a lot of double files... The structure is a little bit trashy. Everything was done in Windows, MSWord, pdf and jpg. However it contains a lot of interesting data that can be preserved this way for people interested in this material.
You can download the binders from the list below. Here is a zip-file with the index for local use: PdB.zip
