You can get a Lepai TA2020 amp off Ebay very cheaply. They sound good straight out of the box but to get the full potential a little hot rodding goes along way 
Marked on the PCB are all the component values. When I started to look at the components they didn’t match up, i began measuring with my multimeter… Then I started replacing things……… (click pic).

hey col, been a long time since the last minirig post!
was the sound much improved? you replaced the pots as well - what with?
looks like a funky litle amp - i might have o get one to replace the poor sad NAD amp that i accidentally blew up (was my bedroom stereo amp)
i think i’d completely bypass the tone control network too.

the pots are very poor quality. I replaced them with Taiwan Alpha, much better and still cheap. The tone controls are fine once they are correctly implemented. The sound is quite remarkable for such a cheap amp.

Good job, been checking these out on ebay. I’d like to put 3 in an enclosure with the a pc power supply (just use the 12volt supply) and make a surround sound amp for my sound card so I can use it with my projector for my home theater. I’d like to put the bass(sub) and the center channel on the same amp, the front speakers on one amp, and the rear speakers on one amp.
Can one of these drive a small subwoofer? I don’t want a lot of bass, just enough so I can hear it that it is there.

Lepai doesn’t have the uumph for powering a sub in a multi amped system as usually the sub is the least effcient of the drivers and requires more power. Why not use the Sure Electronics 2*100W.
