Audio Electronics by John Linsley Hood - your public library should have
a copy. It makes interesting reading and has a few interesting power amp
circuits.

I'd add that if you wish to explore this topic, and perhaps be able to
design/understand/modify then the other books by JLH, and those by Doug
Self may well be useful.

For your first amp you might be better using a kit such as:

than you would by just buying a decent amp but any hobby takes time and
money, and listening to your own work gives a certain satisfaction.

Their kits are also useful as an easy starting point for some of the 'bits'
if you want to experiment. You may be able to find most of the items
cheaper elsewhere, and find a wider diversity, but they can be useful as a
'first stop' for things like a case or heatsinks, etc, if you don't want to
search for all the bits needed.

Slainte,

Jim
