On this page, I will only talk about how I build my gainclone,
and show you my gainclone. I will not discuss on how it works, or
how to build it yourself. Please do not try this if you have no
What interests me is the simplicity of how an amplifier can be.
There are very few components, so few that most DIYers don't even
need to use a PCB, but instead do it p2p - point to point soldering.
With so few components, an experience person could solder a gainclone
within an hour.
There is no need for large caps, in fact the recommended value
is only 1000uF, which makes the whole amp very small. Yet even with
such few components, it is a very good sounding amp - many people
What really got me starting was when I saw one of Peter Daniels'
I can't believe how beautiful a DIY amp can be.
Soon after, I decided to try out for myself. I did some research
and found some schematics.
One can use as little as a bridge rectifier, 2 caps, 2 resistors
and an IC for Gainclone Lite. However I did not choose this because
there are DC offset at the output, and I don't like the idea of
having the woofer always pushed or pulled.
I got this schematic from somewhere (I forget where) This looks
good, but it seems to have a little too many components.
I edited the schematic from the recommendations given by some people
at diyAudio. I removed the
volume control because the volume will be at the preamp. The output
resistor is not needed, and the 1uF decoupling cap is not needed
because the 1000uF will be very close to the IC. I risk having no
DC blocking cap in the input because most cheaper caps degrade the
sound by a lot.
