The Mullard factory in Blackburn occupies an area of 45 acres. Most of Mullard's receiving valves are produced there. To achieve the highest level of quality control, in the primary stages of production, glass and filaments are also manufactured here.

Behind the Mullard brand, there is Britain's largest and most modern industrial complex, in valve, picture tubes and semiconductors.
The Mullard complex is made up of 14 industrial production centers, many of them located among the most advanced in the world; a central electronics laboratory, employing some eight hundred researchers, and the "Center for Electronics" as it is known in Britain, the organization's true headquarters. Mullard is endorsed by the prestige of its high quality and high performance.

Thank you Gerhard,

Ok, I hadn't found it. An administrator can then delete my wrong picture.

Unfortunately I can't do it myself.

Best regards,

This comes much closer to the arrangement of houses on the old picture.
