Very early British X-band
klystron. About 100 units made. |
|
CV119 |
Bolometer, radiation indicator |
|
CV240 |
High-power VHF micropup triode.
Likely the biggest micropup tube made. |
|

|
CW10
- OSRAM |
Magnetron, split anode, about
1935. Likely designed by Megaw and used in the early experiments on microwave
radio-detection. |
|
DV27 |
Early S-band Heil oscillator.
Likely experimented as local oscillator in S-band RDF receivers. This is the
only sample still surviving. |
|
DV57 |
Early X-band Heil oscillator.
Likely experimented as local oscillator in X-band RDF receivers. This is the
only sample still surviving today. |
|
E1189 prototype |
Very early 8-cavity magnetron
prototype, GEC. This is the first laboratory unit of the 8-slot design to
operate around 30 July 1940, while assembling the No.12 brought to America by
the Tizard Mission. |

Eight-cavity strapped
developmental magnetron. Likely made in 1941 at Birmingham by the Sawyers
group. |
|
RM 4025 |
German WWII experimental
internal resonator magnetron, 3 cm |
|
