Hi
Do we know for sure that Racal actually made these OCXO's in house?
My *guess* is that they were made by various companies over the years and
sold to Racal. The "return for service" would have been a return to Racal
and then they forward it to the people who made it...
Having just been inside one Bob, I can say for sure, yes, they were made
by Racal at I presume Bracknell, the sub assemblies all have racal style
part numbers and use similar components to a lot of the instruments of
that period.
Also having just been in a 9420 I can totally see why they didn't want
anyone mucking about inside it. I suspect like the -hp- 10811 there
were some adjust on test values that depended on the individual
crystals. But all that doesn't apply to us time nuts does it? I
didn't consider myself a true "nut" until I'd been inside and fixed a
dead 10811 with an open thermistor :^). In any case Racal as such is
long gone and there's no one to return them to any more so we don't have
a lot of choice.
