BBC condenser microphone, c.1934. Before miniature valves became available, the need to provide a pre-amplifier near the capsule of a capacitor microphone could lead to excessively large assembly. In this example, the shape of the casing was designed to minimise the acoustic ill-effects of its large size.
From 1931 to 1935, the BBC used this streamlined condenser microphone known as "the bomb", which employed a Western Electric or STC capsule but had a BBC pre-amplifier.
