Custom Amplifier for PC Audio

[Matt420740]

Just started building a new 2.1 channel amplifier for my PC sound system.  18W x 2 @8ohms for left and right channels, and 30W Subwoofer output @4ohms. 

 

The amp is a TDA2030 based board I bought off fleabay.  The enclosure is salvaged from an old Cooler Master 300W PSU, which was perfect because it already had a 120V IEC power connector, and power switch installed.  I pulled out all the guts but left the plug and switch to re-use since I'll be powering this with 120V AC from the wall.   

 

To get the correct AC voltage to feed the on board rectifier I'll be using a toroidal transformer from Antek.

 

Here are a few pics of the build -

I'll get some more pics up soon as I get everything buttoned up.  Still need to install a fuse on the AC input, and get some grommets for the transformer wires.  Also still waiting on the subwoofer to arrive.  Going to go with a 6.5" 4 ohm Sub.  Using Pioneer 5.25" 3-way speakers for the left and right channels.

Heres what it will look like when finished.  Still waiting on the sub to be delivered, then I'll see what this thing can do.
