Hints for removing blown TDA2822

Many constructors have suffered the failing TDA2822.   Today, few will have this experience as the v4 board doesn’t use the TDA2822 at all, but discrete transistors in the audio amplifier.

If you have a blown TDA2822 then it helps to know how to remove the blown chip.   Advice from other constructors is:

  1. Cut off the legs of the chip as close as possible to the chip itself
  2. Hold each leg tightly with pliers, while heating the soldered end on the board.  Wiggle the leg until it comes out.
  3. Clean up the holes using a solder sucker.
  4. Install an 8-pin DIL socket to hold a new TDA2822 or one of the potential replacement chips.
