Hello all, I am currently trying to build a CMoy amp using Tangent's Layout, and am having a problem with the power circuit.
I currently have C1 and C2 jumpered so I could rule out any polarity problems, and I took out the LED (but kept the 10K resistor) for the same reason (although I'm sure the LED is set up as the right polarity for obvious reasons).
I am current getting 9V on the + and - rails and 0.09V across C1 and C2. If I break the circuit across the + and - rails, I get the full 9V across C1 and C2. I am also getting about 0.09V across the juncture between either R2 and R3 and the virtual ground, but I am absolutly positive I am using the right value resistors for R2 and R3 (according to my multimeter).
Any idea what the problem could be? I've been staring at the back of the board forever, and I am positive that it is not a short circuit from my soldering.
