Home-constructed Williamson amplifier, c. 1949

In 1948, vinyl replaced shellac for making gramophone discs, bringing near-silent sound reproduction. As a result, audio buffs needed better-quality amplifiers. This high-fidelity amplifier was designed by the British electronics engineer Theo Williamson. Instructions on how to built it appeared in the technical magazine 'Wireless World'.
