I just received some 8pin dip sockets along with the NTE7155 audio

My TDA2822 just went up in an impressive display of smoke
and sparks---glad I had the top of the case off so I could
see it. This board was shipped March 9th. It's a WX chip
soldered directly to the mainboard. This happened in the
2nd test run, after about 5-10 minutes of use. I think it
was on for about 15 minutes grand total since I assembled
Now it's time for me to arrange a fix---I guess I'll search
through the archive to see what approach is best. For what
it's worth, we bought an early uBITX back in December and
used that one a while with digital modes without any
issues. I'm guessing that this is consistent with the
theory that some WX chips conk out early.
