TP3 voltage

To get 5.25V on TP3, R26 should be cca 1k66.

But as soon as I ground digital board I get 4.9V on TP3.
Of course, I not grounded there is no music. I really must get those V/I transformers ASAP.

AD1865 - AGND and DGND have to be connected together, if not there is not music. As soon as I do that, voltage on TP3 (Vs+) drops.
