Hari,
An underrated chip. I melted my breadboard but the chip worked on regardless! No instabilities.
See the files section for my RX2 diagram for the audio section. There are mistakes in the diagram, you will have to forgive me!

Raj,
Strange coincidence !
I was having tough time with overheating of TDA2005 and was recommended TDA2822 by VU3YFD and just this week end VU3KMR delivered two of them along with a C6823 , iam going to try 2822 as its stereo and very simple.

Nice to see the 2822 being used for audio amp. Much better than others!
Push pull circuit gives 1W out..
