I get 93mv and 93.5mv across those two resistors, r6and r11, the 2.2ohm parts.. Each time you redial the calvin board you'll need to adjust the trim pots on the main board. Eventually it should all even out.
Si,
'cos I'm stupid...
The aim is to get the voltages across R6 and R11 the same by adjusting the trimmer on the Calvins. Then check the PSU voltages and trim them to be equal at +/-18V. Back and check the voltages on R6 and R11, trim the Calvin to get the voltages equal. Then back to equal out the PSU voltages, rinse and repeat.
