Hi
On an oscillator that is 50 years old, there likely has been some aging of the
crystal
and other components. As you tune the crystal back onto frequency, you can
easily
impact the EFC sensitivity. On *any* older device, “measure” is very much the
right
way to do it.

Hello Tom.
Thanks for your info.
My oscillator comes from an HP-5061a, which I obtained from a company as
the tube was dead.
The log book indicates a start date of 1971, so yes, not a youngster!
I have the full set of original manuals for this 5061A , but the oscillator
specs are not detailed to
Joe,
The 00105 oscillator was used in early hp 105 quartz frequency
standards. So the specifications, theory of operation, photos and
schematics for the 00105 "brick" oscillator are all in the hp 105 op/svc
manual (April 1968).
There are two copies on Didier's site. Go to
That is a incredible project, well done !!. EEVblog forum is one of the better

also contributors on EEVBLOG.
