| What Home Entertainment Owes to Intrinsicality |
OK, try and ignore the crap title. This two-part article from Mullard contains some interesting details on the production of CRT's and valves at the start of the 1960's. |
| Power Grid Valves |
A fascinating paper presented by Jack McCullough (of Eimac) in 1965. The history of these valves plus a look forward to the future (from 1965's perspective). |
| Materials and Shapes of Vacuum Tube Heaters |
An article all about the materials and construction of valve heaters originally published in the magazine Electronic Industries magazine in December 1961 |
| Getter Materials | An article on the selection of materials for use as getters, originally published in "Electronics" magazine in October 1950. |
| Microphonics | Extracts from some research undertaken by Mullard in 1962 into the effect of valve construction upon sensitivity to microphonics. |
| Valves at U.H.F. | An article written in 1954 on recent developments of UHF valves and describing the Magnetron and Klystron. |
| Guided Grid Valves | A valve development from around 1960 aimed at high frequency operation in TV tuners. |
| The Nuvistor | The nuvistor was a miniature high-frequency valve introduced fairly late in the life of valve technology. |
| The Manufacture of Junction Transistors |
A Mullard article on the manufacture of junction transistors such as the OC44/45 and OC71 etc you find in many early transistor sets. Its amazing just how labour-intensive the process was. OK, so its not valves but it is valve era. |
You can find a lot of similar interesting articles on John Atwood's One Electron website (refer to its Archive section).
