Mike,

I've never tried to open up a DC-8.  After years of testing FT-243's for 
BC-611, BC-620 and BC-659, 100% of the failures found have been caused by the 
brass leg of one or both of the contact plates breaking somewhere between the 
plate and where it is soldered into the pin.  However, if the dud DC-8's are 
constructed like the one in your photo, that (breakage of leg) doesn't appear to be 
a possibility.  You might however try heating and resoldering the two pins 
before opening one up.
