Default Music Angel XD 500 MkII Bias setting

I have a Music Angel XD 500 MkII amp that is used as backup to my main system. I have never re-biased it since I bought it used, 2 years ago, and don't know the setting I should see on the EL34's.
Tubes are Ultron (RFT) EL34. All test fine and matched on the Avo tester.

Help would be much appreciated.

If you searched this site, you would find stuff like this. If you have 22 ohm cathode resistors, you want to read about 0.88 volts across each one to give 40mA quiescent current per tube.
