  This is my second Gainclone amp, after my first. This one is also based on a brianGT kit but it uses the LM3886 IC which is more suited to 4 ohm loads, unlike the LM3875. It will output 70 Watts into 4 ohms. This version also uses a very high capacitance PSU and a snubber.

You can see great discussion about the snubber idea here.

I made it entirely out of recycled metal bought from scrap metal yards, you can see some of the metal has deep scratches still. I dont mind, I think it looks kind of cool:

Here you can buy the same kit:
