Box E.1

Mullard describe the E810F as a special quality high slope pentode designed for use in industrial equipment where stability of characteristics and long life are required.

It is a wideband RF device, but no frequency range is given.

From the information available it appears that 40 – 100 MHz is a probable upper value.

Oscilloscope amplifiers and other measuring instruments are likely candidates for this valve.

We believe that this valve dates from the 1960s.
