Just had a quick read of the Theory of Operation and Calibrations setions of

R250 is to set the DC level of the triangle wave before it goes into the
triangle to sine converter. It needs to be set with a distortion meter, so
don't touch it for now.

The DC level at the output is set with R485 (DC Bal).

You’re right. I don’t have a distortion analyser. Not a good idea to mess with that at the moment. It’s only 25mV. I can live with that until I get a descent analyser.
