DIY Audio means "do it yourself" audio. This is when a person makes the audio equipment themselves. Audio equipment is readily available today but a lot of satisfaction can come from making it yourself. There are many companies who cater to this hobby.
Gainclone or chipamp refers to a type of amplifier made by DIY (do it yourself) persons. This amplifier is most popular with hobbyists and has a design of high power integrated circuits, usually the LM3875. The benefit of using the Gainclone amplifier is the simplicity in building and the parts are easily accessible.
The name Gainclone came about because it is a clone or replica of the Gaincard, which was an extremely popular amplifier that was simple and less costly to construct. The design of the Gainclone amplifier is simple to build and the parts so available that even the beginner can build one.

Do you enjoy building things yourself? Find supplies for DIY (Do It Yourself) audio and amplifiers like the Gainclone type. Learn how to build these and even to make a good enough profit that you can start your own business. There is satisfaction in building something yourself and to know that it is well built and not the cheap junk you can sometimes find in stores.
Gainclone sometimes called "chipamp" is an amplifier built by a DIY, (do it yourself) person who enjoys making their own audio equipment. High powered integrated circuits are the best when building these. The National Semiconductor Overture series is the one most used by these, do it yourselfers.
The gainclone amplifier is made from a simple design using a 56 watt chip. (National Semiconductor LM3875) It didn't need the giant power supply like other amplifiers and cost only $100.00 USD to build. It could then be sold for $3300.00 making a large profit.
Now the gainclone amplifier builders can use the National Semiconductor LM1875, LM3875, LM3886, LM4780, orLM3886. The LME series of the National Semiconductor also can be used to produce excellent sound. The best series are the LME49830, LME49810 and the LME49811 and give you the best or equal the sound of all the amplifiers out there.
On a side note: I am thinking about the possibility of someone like you the reader making this into a home business. The idea would be for you to do this on the side and if it works out then you quite your job and do it full time. This may not be for everyone because it takes a lot of work to start a business for yourself and sometimes it is just easier to go to work and let your employer do everything and you just have to show up. But for those who long to be their own boss this might lead to great things.
One precaution. Unexpected things happen so make sure you have enough savings to hold you for at least six months. We do this ourselves and just had an Internet crisis of two of the programs that brought us money to live on. However we have some money set aside and are slowing climbing out of the pit and hope to be going again in a couple months. The first thing is to replace our savings for another disaster before we do anything else.
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
