L0MO 19À4 (lollipop) was made by LOMO in 1958-1968. It was designed for high quality music and speech studio recording as well as for live filming. The microphone can be widely used in radio and TV studios.
It has à head Ì-3 cardioid with à large diaphragm capsule 1.2 inch made of brass.
The amplifier is made on valves 6S6B (1954-1964) and 6S31Br (1964 - 1968). The valves 6S6B and 6S31Br are low frequency triodes and are distinguished by their low self-noise and rather small microphone effect. Valve 6S31Br is à low frequency triode of high reliability. (It is an improved version of 6S6B.)
The microphone is supplied with à massive PSU type BP-2 switchable for both 110V and 220V.
