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.
