I would recommend putting the voltage regulator in the supply line to the TDA2822.  I did that before applying power to my kit and have not had a problem since then.  I have very high volume levels if I need them.  The TDA2822 is a good amp when supplied this way. I have also put a mod in to minimize the click and pop produced between transmitting and receiving, and an AGC circuit with RF gain attenuation control that has been a great help.  To my ears the receiver is very acceptable now.

Here is the link to that regulator mod:
