Extras ▼

 

The EF95 is a low noise RF voltage amplifying pentode, designed to operate at VHF. Mullard introduced the valve in 1952 as a direct equivalent to the American 6AK5. This exhibit is unbranded.
The quoted noise factor at 180 MHz is 3.5.
See 6AK5 for more details.
See also M8100 for the special quality version.
The folded anode is stitched on one side. All three grids are visible. The getter holder is flared to disperse the material evenly across the top of the envelope.
A closer view of the three helical grids.
The thin glass tube envelope is 18 mm in diameter and excluding the B7G base pins measures 36 mm tall.
References: Data-sheet & 1040. Type EF95 was first introduced in 1951.
