I monitored the bias voltage over time

And it slowly declined after about 5 minutes. The coupling caps are 2 brand new Mundorf Silver and Gold in oil. The voltage rating on those are 800vdc so i seriously doubt that it is defective. The 10R resistor is a 2 watt unit and i did check it at the same time and it was not even warm, so again, doesnt appear to be a problem.
