Does the Audio Research PH-3 Invert Polarity?


I just recently bought an ARC PH-3SE and so far I am very happy with it. I was surprised to see that the owner's manual does not mention polarity. Does anyone know if the ARC PH-3SE inverts polarity? Thanks.

Looking at the schematic, there is a FET gain stage followed by a cascoded tube gain stage, followed by a cathode follower output. Ergo, two gain stages means it does not invert phase.
