The schematic for a more versatile EFC translator circuit is attached.
Any EFC range in the -10V to +10V range can be accomodated.
Even greater EFC ranges are possible by using a suitable opamp for U103
with appropriate power supplies.

The messy details of power supply bypassing etc are left as an exercise
together with calculating the necessary values for R107, R108, R109 for
OCXO EFC ranges other than [-5V, +5V].
Hint: select R107 to set the EFC span and either R108 or R109  to set
the EFC offset.
