Well copying someone elses work probably isn't going to get you much of a mark?. But try here! http://www.ampslab.com/projects.htm

Here is the list of ic's. little old but ok.
Now new development r class D based & not suitable for newbies.

How far would I need to drive to buy old low power Russian amplifier ICs?? About 20,000km?

Is there anyone interest with creating new Hi-End Audio Amplifier thread?
I've initiate it, but I've no access to do it.

I'll help to start it with my 7th version K32 that been fixed in dec2005.
And also analyze old halcro schematic.

audioguru

There are lots of good audio amplifier schematics on the web.

But not here. Nor the halcro's.
Just want to offer.

How about this historical article:
http://www.edexcel.org.uk/VirtualCon...list_units.pdf
"High Performance Audio Power Amplifiers for Music Performance and. Reproduction (Butterworth-Heinemann, 1997)".
It contains much great invention and schematic, also devices.

tda2005 or lm2005 is not really effetive 20 watts power output... it is usually used for a booster amplification in car audio....

skydemon2008

is there any other better power amp that can be used for a radio? what is the suitable power range that can be used for a radio?

audioguru

The power range of an amplifier has nothing to do with a radio.
Unless you are worried that a speaker that is strong enough for high power is too big and heavy for a little radio.

You can make an amplifier with thousands of watts of power. Then you can use a powerful speaker like this very powerful Jackhammer:

In the schematic, pins 1 and 2 are reversed. It won't sound good if assembled according to this diagram. It cross-references to an NTE1396 ( 11-pin SIP).

Car radio amplifiers are bridged and deliver about 18W per channel to a 4 ohm speaker at clipping with a 14.4V supply. Even the ones that advertise 200 Whats.

Philips have some car radio amp ICs with a voltage doubler for nearly 4 times more power.

Really simple! No part numbers or component types. Maybe 45 watts square wave into 2 ohms. Do you enjoy square waves? They are a bit harsh for my taste.
