Maplin do all sorts of modules if you are able to wire these up to a PSU.

Where might I go for basic audio amplifiers?

All I want is something that has a 3.5mm input jack, and speaker
connectors.
Everything else, perhaps even a volume control, is extra.

Something around 20W.

This would be for miscellaneous household audio.
At the moment I've got various stereo units doing this, but they are
rather
large, and a neater solution would be nice.

Thanks.
