Hello

Am building a Dual Stereo Buffalo DAC with legato output IV stages.

Now, i have got the second DAC just installed now, and I was just wondering what the CORRECT currents for the Placid supply should be.

All set to 15v, no problem. VR2 Adjusted.

Now adjusting VR1 would change the CCS measured voltage (which is the current), mine measures 220 mv, which is 220ma
Shunt is 40mv / ma

on the other supply / DAC its CCS 400mv and 230mv shunt.

Do I need to adjust VR1 to get it up to that point? Just tryign to understand this a bit better What is the correct setting for the Legato?...
