Yes, try a 1K pot across one of the resistors and see which way the offset goes. If putting the pot on one resistor lowers the offset then turn it down....if it raises the offset then put it on the other resistor and then turn it down to zero it and then replace the pot with fixed resistor. The offset will drift with some time so let it burn for a while with the pot in there and then re-adjust the pot a little and then replace with fixed resistor.
