As you can see, there are two separate gain selections determined by which set of emitters is chosen, pins 1 and 16 or 2 and 15.   
As you can see, there are two separate gain selections determined by which set of emitters is chosen, pins 1 and 16 or 2 and 15.   
This selection is made off chip by choosing Q205 or Q215 to carry the current through R212.

Pot R217 allows dc balance at 5mV/div to match that at all other sensitivities, controlled elsewhere.
