[Elecraft] K3 board - lack of modification version control

Would you care to elaborate?

In the past when I worked for one of the large European manufacturers 
they had very strict version control, when a change was implemented the 
updated version number was written in black marker on the board, with 
the board number followed by "/01", etc. In the case of military kit, or 
kit that may be used by the military, there had to be a "mod state" 
plate on the outside of the equipment too.

I received a replacement PA and driver board from Elecraft and there was 
no way to distinguish the updated driver board from the earlier one! The 
PA was easy as it had two resistors in parallel in place of the single 
ones at (I guess) R4 & R5... But no markings that were obvious to me.
