Frank Philipse has produced a truly comprehensive collection of valve data sheet PDF's and these can be found on his site Frank's Electron Tube Pages. Click the logo above to go to his site.
We are pleased to offer a mirror site for data sheets that relate to our exhibits. Frank has gathered as many datasheets as possible for each valve type. We aim to present, in English, the datasheet that matches our exhibit wherever possible. For example for a Mullard valve we will present a Mullard sheet or a Philips sheet if available.
Many thanks to Frank and his colleagues for providing the resource and allowing us to make use of his research.
