Onixia
300va Toroid 2x25v
2x56watts LM3875
Panasonic FM caps 1500uf/10uf
Panasonic Resistor’s
Elna Cerafine 4.7uf DC blocking Capacitors
MUR860 OnSemi Diodes
Earlier this year i decided to start a new D.I.Y Audio project, I wanted a small yet powerful amplifier for the PC to power a pair of Q Acoustics 1010i bookshelf speakers. I decided a Gainclone was the way to go.
The principle of a Gainclone is simple use the least amount of components in the signal path possible! I decided on the LM3875 PCB's from Audiosector. Peter is a great force in the DIY Audio world and is a master at making simple yet beautiful chassis’ as well as the bits inside :)
So the Gainclone boards were assembled and the prototype chassis was made to house and tweak the layout .After a week or so i had the layout down and i knew the dimensions of the chassis that i required. I already had decided that i would need to make my own chassis and here it is.
Â
I guess a D.I.Y. project is never really finished and is always ready to be tweaked in some way or another. Already I have capacitor rolling in mind and maybe a onboard DAC powered off a custom winding from the main toroid along with a CNC 12mm aluminium front panel .

- Hi there Koogar!
Amazing case! Is that solid marble? Where did you get the knob?
