Tom,

In those instances, the details of the debugging were likely taken 
off-list.  I cannot recall those exactly, but I believe they were resolved.

When doing off-list debugging, I leave it up to the indivudual to report 
back to the list with the resolution.  Some do and some do not.  If 
reported to the list, it was likely in a new thread.

I am concerned about the heating of U1, and that is what you should 
tackle first.  Check the voltage at U1 pins 1 and 20.  They should be 
close to 6 volts.  Also check the soldering at the U1 socket to be 
certain you do not have a solder bridge.

73,
