| Description |
Tyne calls it FE2. Either Tyne or Thrower may be in error. However Fellows/Louden advertisements of the 1926-27 period refers to them as F2. The FE series were introduced as dull emitter equivalents.
Louden valves were marketed by Fellows Magneto Co. Ltd. from 1924 to 1927.
The F1, F2, F3, Bright emitters were replaced by the near equivalent FEx1, FEx2 and FEx3 series in 1926-27.
