The EF184 is a purpose designed high gain VHF frame grid pentode. The EF184 was introduced in 1960 and superseded the EF80. The mutual conductance is 15.6 and the closely related (pin compatible) variable μ pentode EF183 has a μ of 12.5.
The valve could be used as an RF amplifier for 405 line television receivers or band two FM radios. We have no details as to its noise performance.
The thin glass tube envelope is 21 mm in diameter and, excluding B9A base pins, is 53 mm tall.
