The name was first coined by a poster called "triodont" (Ramon Salamat) on the popular Audio Asylum board (ca. The DIY community started building replicas or "clones" of the Gaincard using integrated circuits from National Semiconductor and other manufacturers in an attempt to see if good sound could be obtained, thereby the term: "gainclone". Controversy ensued after a number of positive reviews. This Gaincard was estimated to cost less than 100 USD in parts, but it sold for 3300 USD with its small power supply. These construction techniques went against the accepted wisdom of the time, which favored large power supplies and discrete component construction. It had fewer parts, less capacitance and simpler construction than virtually anything preceding it, and relied for amplification on a 56- watt chip, the National Semiconductor LM3875.
The Gaincard shook the audiophile community with its unconventional design. In 1999, 47 Labs introduced the Gaincard amplifier.
As an amplifier it is highly regarded by many in the DIY community. It is simple to build and involves only a few readily accessible, inexpensive parts. The Gainclone is probably the most commonly built and well-known amplifier project amongst hobbyists.
It is a design based on high-power integrated circuits, particularly the National Semiconductor Overture series. Gainclone or chipamp is a type of audio amplifier made by do-it-yourselfers, or individuals interested in DIY audio.
