The OM6 is a screened variable μ pentode designed for radio receiver use. The frequency range of operation would be up to 30 MHz and it was used as an IF or RF amplifier.
The OM6 is directly equal to the Mullard EF39.
The classic envelope is 31 mm in diameter and excluding the IO base pins it is 84 mm long.
