I found a cracked solder joint in a TR-7 PTO not long ago, using a method
similar to Eddy's. The connection appeared entirely normal, except that the cut
end of the wire poking through the solder seemed to be bent at an odd angle.
The symptom was intermittent PTO operation, and the cause finally presented
itself when the solder joint in question was 'stimulated' with a non-conductive
tool.

Orange wood sticks work well for such probing, they are soft enough that you're
not going to hurt anything.
