I personally take issue with the tech levels...

I think they make to much possible at lower levels.

A should be anything that takes a computer to run it or manufacture it.

Such as a Fire Control System (FCS) on a modern (1990s) Main Battle Tank or the Computer Numerically Controlled (CNC) automated mill or lathe.

This a some advanced plastics like polymers, also lightweight alloys .

This and computer repair.

Tech level B should be able to repair solid state or vacuum tube tech, right up to silicon wafers and CPU mother boards.
