The TT-1 was the heavier, overdesigned model.

The TT-1/A was the cost-reduced version, and a better compromise
between what the military wanted and what the taxpayers could
afford.

This opinion is worth what you paid for it.

 Does anybody know the actual difference between the Heath 
TT-1 and the TT-1A tube tester?  Is the addition of the newer
 sockets in the lid the only difference?
 
 Thanks, Scott W3CV
