The pot will adjust them slightly, but not level there is a fixed resistor that has changed value. If anyone has a readable schematic, I would appreciate you emailing me a picture of it.

   Lacking the correct answer:
   I don't know the 'scope, but frequently trace rotation is 
accomplished by a coil around the neck of the tube right at the bell of 
the CRT, if you have such a coil, perhaps you can trace it's wires back 
to the circuit that provides a temperature compensated constant current 
to this coil.
