Valve Ephemera: Mazda Factories
Some of these shots are the early Ediswan (Edison Swan)  factories that were taken over by Mazda in the early 1960s.

This 1958 photograph is from  part of the valve mass production assembly line at one of the old Siemens Ediswan Sunderland Factories.

This is reprinted in the 1964/5 Ediswan Pictures captioned "Assembling Mazda valves at Sunderland "A" Factory"!

I count at least thirty lines of 14 workers - meaning there must have been at least 420 people in one room!  How did they all clock out?

"Quantity production of Mazda CME1903 picture tubes at Sunderland 'B' Factory"

This CRT was a 19" rectangular face screen.  The heater was 0.3A, 6.3V and it boasted: Short neck, 110 deflection, electrostatic focus, straight gun, external 'dag, aluminised screen, grey glass with a light transmission of 75%.

I'm not totally sure what this huge machine was but the large bed obviously slid inside.  It may have been an oven for curing the phosphor coating or something.  Any ideas out there?

"Mazda Twin Panel CME1906 picture tubes coming off the panelling line"

This CRT was a 19" rectangular face all glass twin panel screen.  The heater was 0.3A, 6.3V and it boasted: Short neck, 110 deflection, electrostatic focus, straight gun, external 'dag, aluminised screen, grey glass bulb and panel with a light transmission of 65%.

A page from the 1964 Mazda data book boasts of its great (bought) heritage.

Sixty Years Back

"Professor Sir. Ambrose Fleming and is original diode valve, made in the Edison Swan (later Mazda) factory at Ponders End near London in 1904.  Professor Fleming was Technical Consultant to the Edison Swan Company at the time.  It was this close co-operation between University and Factory which resulted in the first radio valve in the world."
