Got mine going with a 15 volt 3 amp supply from an old Toshiba.
That and 5 volts.

It took about 32 minutes to make lock.  Before that it was
cycling between about +75 and -200 Hz.

The FE-5680A 10 MHz is now off by .002 Hz compared to the Thunderbolt.

I placed a magnet on the case.  It appears I can fine tune the frequency
by adjusting the position and rotation of the magnet.

Film at 11.
