Looking for a simple power amp

[mnordbye]

I'm in the middle of designing a practice amp, and i'm looking for a power amp to go with the preamp i've decided on. What i need is something that pumps out about 20 watts and is cheap when it comes to components. I guess i'll go the transistor way.

Can anyone point me in the right direction for a schematic or a layout?

a 20w ss amp can be obtained from using a single LM1875 25w TO220 IC
here is a couple schematics on how to use this thing





the LM1875's data sheet

and some pictures of the 20W AUDIO AMPLIFIER MODULE from siliconchip.com.au

Oh, that's really something. Thanks! I suppose i have to use mains voltage with that?

Enormous heatsink by the way..
