Electronic Valves
December 12, 2011
A Valve is a device in a glass case that relies on the flow of electric current through a vacuum. Valves have many uses in a wide range of vintage electrical machines such as radios and amplifiers. Valves may be used for rectification, amplification, switching or similar processing. It is therefore not surprising that the amplifier (below) has captured the attention of the male admirers surrounding it.
