The 12BH7 double triode is pin compatible with the ECC81, ECC82 and ECC83 series from Mullard but has slightly different characteristics. Brimar give the intended use as TV frame oscillator and frame output. The construction is compatible with audio through to low VHF use.
The thin glass tube envelope is 19 mm in diameter and, excluding the B9A base pins, is 68 mm tall.
