Before you tear into the OCXO, have you checked to be sure it is
properly connected and set up, and its working conditions are right?
There must be a BNC jumper on the back to connect the 10 MHz, and the
reference selector switch set to internal.
Furthermore, the power to the XO section is not turned on until the
OC is warmed up, so a quick checkout may wrongly point to OCXO
failure. There is an indicator LED in the power supply circuitry that
shows when the XO power is on. You have to leave the 8566B plugged in
to the mains for at least ten to fifteen minutes to be sure it will go.
