The OM10 is a triode hexode frequency changer for radio superhet receivers. The heater is both 6.3 Volts and 200 mA so is suitable for both parallel and series heater arrangements. The Mullard equivalent is the CCH35 and this is defined by its 200 mA heater requirement.

The classic envelope is 32 mm in diameter, and excluding the IO base pins is 92 mm tall.
