Also it appears you have an unused secondary for your 5V supply. I would carefully (observing polarity/phase) parallel the two secondaries to increase the current available to your placid.
Using both the secondaries pair to power the Placid?
Russ White;5174600 I would test it by removing it from the rest of the circuit and connecting the inputs to GND. [/QUOTE said:Do you mean connecting are the inputs from the B-III as shown?

Do you mean connecting are the inputs from the B-III as shown?
Yes - while you are testing it separate from the other circuits.
With the inputs connected to Gnd as above and nothing connected, I got these measurement :
Left Output:
SE Output :
SE and Gnd : 319.8mV
Balance Output :
+ and Gnd : 157.2mV
- and Gnd : 165.2mV
Right Output :
SE Output :
SE and Gnd : 1.965V
Balance Output :
+ and Gnd : 0.979V
- and Gnd : 0.984V
I can't get my finger to the OPA1632.

Another thing I did observed is that when I switched the Placid BP from the right output into the left input of the IVY-III and the left output to the right input, the voltage drop right to about 1.5V.
I am not sure what you mean here.... Why are you connecting the power supply to the signal inputs/outputs?
Very bad ....
Oooo! You're showing that you are taking the positive voltage output of the placid and inputting it to the negative power input of the IVY, and the negative placid supply output into the positive power input of the IVY
That will probably destroy the OPA1632 !
Maybe the drawing will help me explain better,

Oh. ****. Shouldn't the Placid limits the current or voltage?
I don't know. Why not switch the plus & minus voltages to the the way they should be and see if it is ok? Nothing to loose at this point. Maybe the gods of audio will smile at you
