The forward-biased (junction) voltage for silicon diodes is 0.7V in most of the circuit analyses, but it can dip to as low as o.6V because of the construction of diodes is not perfect. As for germanium diodes, yes it's 0.3V when forward-biased.

For the op-amp configuration, try to check the feedback network first, maybe the feedback pot (if there is) is not adjusted to the right value or it is open/broken already...if this is OK, your op-amp may be is at fault.
