Default How to adjust the Bias on Mark Levinson 27.5 amplifier?

I have newly aquired a used 27.5 and need to adjust the Bias on both channels .
I have the schemtics and some description of the circuits , I think it is R114 which does the bias adjustment but not sure what should be the voltage acrosss Emitter resistor points... in my previous ML29 amplifier it should be +26.4 millvolts

Thanks for any help!

Georg
