Gainclone

The Amp Itself

What is a gainclone without building the amp itself? I chooses LM3875 because it uses the least pins, therefore it is very easy to solder everything up.

As there are very little components, this is all the space I need. Star ground is just able the IC. The feedback resistor is soldered nearest to the IC, just when the leads comes out of the IC. Input resistor is soldered just beside the feedback resistor. The other 2 resistors are there just to maintain the DC output, so it can be soldered a little bit farther away; but as you can see, they are as close as I can get.

I try to get the capacitors as close as possible, thereby the L shaped layout, where the lead near the capacitor just touches the voltage in of the IC. The cables are then wired directly to the pins or the lead of the components, and wired to the socket or diodes.

The Final

I'll leave you with the pictures of the completed amp.
