| DIY Audio means "do it yourself" audio. Rather than buying a piece of (expensive) audio equipment, such as an
amplifier or high-end cable, a person makes it himself. The benefits of doing so include economic concerns, the satisfaction of
creating something enjoyable, and the possibility that the equipment made is of higher quality than commercially available products.
Audio DIY came to prominence in the 50's to 60's, as audio reproduction was relatively new and the technology "complex," audio reproduction equipment, and in particular high performance equipment, was not offered at the retail level. Kits and designs were available for consumers to build their own equipment. |
Famous vacuum tube kits from Dynaco, Heathkit, and McIntosh, as well as solid state (transistor) kits from Hafler allowed for consumers to build their own hi fidelity systems. Books and magazines were published which explained new concepts regarding the design and operation of vacuum tube and (later) transistor circuits.While audio equipment has become easily accessible in the current day and age, there still exists an interest in building one's own equipment, including amplifiers, speakers, preamplifiers, and even CD players and turntables. Today, a network of companies, parts vendors, and on-line communities exist to foster this interest.
In modern times, integrated circuits make construction of DIY audio systems easier, but the proliferation of surface mount components (which are very small and difficult to solder with a soldering iron) and fine pitch printed circuit boards (PCBs) arguably make the physical act of construction more difficult. Used test equipment is readily available for purchase through the Internet and enables convenient testing of parts and systems. Specifications of parts and components are readily accessible through the Internet including data sheets and equipment designs.
It has become easier to make audio components from "scratch" rather than from "kits" due to the availability of CAD software for printed circuit board (PCB) layouts and electronic circuit simulation. Such software can be free for a trial version. PCB vendors are more accessible than ever, and can manufacture PCBs in small quantities for the do-it-yourselfer. In fact, kits and chemicals for self-manufacturing one's own PCB can be obtained. Electronic parts and components are easily accessible online, and speciality "high end" parts vendors exist.
On the other hand, a wide variety of kits, designs and premanufactured PCBs are available for almost any type of audio component.

| Newnes Linear IC Pocket by R. M. Marston "Newnes Linear IC Pocket Book is aimed at all engineers, technicians, students and experimenters who can build a design directly from a circuit diagram. In a highly concise form Ray Marston presents a huge compendium of circuits that can be built as they appear, adapted or used as building blocks. The devices used have been carefully chosen for their ease of availability and reasonable price. The selection of devices has been thoroughly reviewed for the second edition, which contains approximately 350 new diagrams. Marston deals mainly with strictly-linear ICs such as op-amps, pre-amplifiers, power amplifiers, signal-conditioners and power supply regulators, as well as various hybrid types: the 555 timer IC, bar-graph display drivers, CCD delay lines, function or wave form generators, phase-locked loops and power control ICs. The subjects are treated in an easy-to-read, highly practical manner with a minimum of mathematics."

Dear DIY Audio Fans,I am writing to you in behalf of your Heavenly Father. He is seeking you like a lost sheep. You remember the Bible story? It is about a shepherd who has 100 sheep. But when he brings the sheep home one night, one is missing. He then leaves the 99 sheep and goes out into the wilderness until he finds that lost sheep.
In this parable the shepherd goes out to search for the one lost sheep-the very least that can be numbered. So if there had been but one lost soul, Christ would have died for that one. To read more click Lost Sheep
