I just discovered that I mixed up the 490K and 240K resistor (#22 and 23 on the schematic).. had them reversed. Could that be the cause ? Here is a photo of the caps I am using and of my center tap (Yellow and green)

I am also ashamed to say I had a 500ohm resistor instead of a 500K. Newbie mistake.
Will replace them tomorrow. Do you think this could be the cause ?????
This picture explains where the error was..
