[time-nuts] Is this ocxo salvageable?

My Bliley square wave 10MHz OCXO was working just fine for close to 30
hours until a few hours ago. Now it puts out a rather noisy waveform about
one volt peak to peak.
Two questions:
(1) Are these things repairable, the metal can is soldered.
(2) As you can see in the attached oscilloscope photo the OCXO still puts
out a strong 10MHZ component. What is the best way to filter this and
recover a good 10MHZ square wave?
In the linked photo, both channels are set to 1 volt per division. The
large sine wave is from a Trimble Thunderbolt and the smaller wave is from
the failed ocxo The EFC is left open (disconnected) and a you can see the
frequency is spot on 10MHz.
