The 30P12 beam tetrode was designed as a single ended audio amplifier output valve for television receiver use or as a TV frame scan output valve.
To operate successfully on the low anode voltage available in a TV receiver the valve has to operate at higher current to achieve the target output power of around 2 Watts.
The valve is lettered as BVA and Made in England. The control grid is fitted with a small cooling fin, seen at the top.
The anode is flat across the working faces.
The thin glass tube envelope is 21 mm in diameter and, excluding the B9A base pins, is 68 mm tall.
