Where can I find detailed info on power amplifiers ?
theory and practices, which chapters ?

 

Try the library.

 

TekTalk, here are a couple sources to get you started:

http://www.rocketroberts.com/techart/amp.htm

http://www.google.com/search?hl=en&lr=&q=%...ifier%22+basics

Some books to get through interlibrary loan:

RF and Microwave Power Amplifier Design
by Andrei Grebennikov

High-Power Audio Amplifier Construction Manual
by G. Randy Slone

 

Hi,

If you are after info on audio power amps. go to the Analog Devices site and download AN-211, which describes a current feedback power amp. The doc is scanned, though, so the images are hard to make out.

 

For RF Power Amplifiers, The Radio Amateurs Handbook from the American Radio Relay League has a good introduction.
