Retrotronics
Encyclopedia
Retrotronics is the making of electric circuits or appliances using older electric components, such as vacuum tube
Vacuum tube
In electronics, a vacuum tube, electron tube , or thermionic valve , reduced to simply "tube" or "valve" in everyday parlance, is a device that relies on the flow of electric current through a vacuum...

s, Nixie displays
Nixie tube
A nixie tube is an electronic device for displaying numerals or other information. The glass tube contains a wire-mesh anode and multiple cathodes. In most tubes, the cathodes are shaped like numerals. Applying power to one cathode surrounds it with an orange glow discharge...

Relay
A relay is an electrically operated switch. Many relays use an electromagnet to operate a switching mechanism mechanically, but other operating principles are also used. Relays are used where it is necessary to control a circuit by a low-power signal , or where several circuits must be controlled...

An ammeter is a measuring instrument used to measure the electric current in a circuit. Electric currents are measured in amperes , hence the name. Instruments used to measure smaller currents, in the milliampere or microampere range, are designated as milliammeters or microammeters...

Retrotronics is a popular strand within the steampunk
Steampunk
Steampunk is a sub-genre of science fiction, fantasy, alternate history, and speculative fiction that came into prominence during the 1980s and early 1990s. Steampunk involves a setting where steam power is still widely used—usually Victorian era Britain or "Wild West"-era United...

 movement. At the Oxford exhibition of Steampunk art, a third of the works on show had a strong retrotronic influence, from light fittings of period components through to computer keyboards and webcams of burnished copper and brass. Outside steampunk, similar influences are found amongst the retro-futurist scene. A recent musical trend has sought to recapture early 1980s 8-bit game and synthesiser sounds, often referred to as Chiptune

A chiptune, also known as chip music, is synthesized electronic music often produced with the sound chips of vintage computers and video game consoles, as well as with other methods such as emulation. In the early 1980s, personal computers became cheaper and more accessible than they had previously...

) amplifiers, on the ground of sound quality or particular "colour". This is still within the scope of retrotronics, but is on a functional ground, rather than aesthetic. Designs of the 1960s are highly sought after today, and still support a market in manufacturing new valves and replacing time-expired components such as electrolytic capacitor

An electrolytic capacitor is a type of capacitor that uses an electrolyte, an ionic conducting liquid, as one of its plates, to achieve a larger capacitance per unit volume than other types. They are often referred to in electronics usage simply as "electrolytics"...

In the audiophile world, such popularity is justified on the basis of sound quality, the earlier valve amplifier designs were free of such artifacts as crossover distortion

 that beset the early bipolar transistor designs of the 1960s. Despite more recent designs that have removed these problems, the "valve sound" is still preferred by some, who will pay large amounts to achieve it. It's also notable that almost all recent audiophile valve amplifiers make a deliberate display of their valves and place them visibly on show.

Another trend is the mixing of tubes with more up-to-date circuitry; these systems are referred to as a "hybrid systems". For example, in the Netherlands, the TubeSociety employs this technique.

Amongst guitarists, the goal of a "valve sound" is different, a deliberate distortion effect achieved through either over-driving valves, or through microphonics
