Vacuum tube manufacture

Описание к видео Vacuum tube manufacture

This video comes from Tesla company archives and was presented on exhibition called "(Un)forgotten Tesla" in Valasske Muzeum v Prirode in town Roznov pod Radhostem - town where Tesla originated from.

I would like to thank to Valasske Muzeum v Prirode for making the video and for keeping it for future generations.
