The ML4  B4 based output triode, first introduced by Osram in 1929 is descended from the first of it's type - the KL1 of 1926 and like it's elder sibling it  was primarily a professional and military type, little used in domestic applications.

It finds favour as a single valve phase splitter and as an inter stage drive valve for output valves such as the PX4 and PX25 triodes.
