Hello all, first post. I picked up a Polaris last year, and at the moment it appears to be working well in both channels. Before running it too hard with low imp loads (Maggies and Apogees), I'd like to make sure the bias is set correctly, but can't find any info on this forum or elsewhere that specifies the test points for each adjustment pot. Assuming this is a stock unit, does anyone have that info? Thanks!
Hello,
I know this thread is rather old...the corrected schematic has only two notes... "VR1 2K Ohm LIN Key = A" and "VR2 1K Ohm LIN Key = Space 50%". I have been a tech for about 50 years and never seen a notation like these, so I have no idea what the "Key" statements mean, unless they refer to an factory alignment procedure long lost.

That sounds like simulation controls. In the simulator, tap the {SPACE} key to "turn" VR2.
But I am not seeing this "corrected schematic" you refer to.

Sorry for the delay. See my other thread, "SUMO Polaris II Questions" for an alignment procedure. I didn't ask about that; I asked about the LEDs in the circuit and received cryptic and off topic responses. I will post the schematic in a moment
