- Marconi Audio Amplifier, Type 4-VA, 1919 - This is a Marconi Wireless model 4-VA amplifier. The device sent a weak radio signal through four amplifying tubes in succession, transforming it into a signal strong enough to be reproduced through headphones or a speaker. This was among the last products produced by American Marconi before their merger into the Radio Corporation of America (RCA).
