20 Watt Power Amplifier

[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:
**broken link removed**
"High Performance Audio Power Amplifiers for Music Performance and. Reproduction (Butterworth-Heinemann, 1997)".
It contains much great invention and schematic, also devices.

nice

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

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?

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).

a simple audio amplifier that can deliver 45 watts of power if supplied with a dc more than 12 volts say at least 14.4 volts

 

[audioguru]

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.

do you have pcb layout for this?? Well i have a pcb maker but i dont know how to use it...

 

[Ubergeek63]

production radios have not used that crap in many years.

Now they use https://www.electro-tech-online.com/custompdfs/2009/01/tas5706.pdf

Now since you have no way of handling that one, I would recommend https://www.electro-tech-online.com/custompdfs/2009/01/tpa3122d2.pdf

The jackhammer is a marketing gimmick and is a piece of sh*t compared to many subs out there. For high power, look into the SoloX 18" series 5kW RMS, 10kW burp peak.

The SoloX 18'"speaker is a lightweight one (100 pounds). The MTX Jackhammer is more than 3 times its weight and handles more power.

Are these manufacturers crazy? 5,000W RMS and 6,000W RMS in a car?
Good-bye hearing.
