This unit on ebay is made from Racal. The complete unit, oscillator and power supply is the MA259. It is a +/- 5 e-10 day stablity.

This equipment is only good to spend winter time or for museum. Several newer oscillator,like HP10811/10544, have the same characteristics or better in smaller size. The component used ar not the best and you can have fault expecially on the power supply.

I have a paper copy of the manual also for the Sulzer 5A (AN/URQ10).

Hi Ignacio,

I got one of these units, from the same seller (actually it is the
one which is pictured). It had a broken connector and a dent in the
cylinder casing.

Luckily the unit powers up! And it generates the frequencies it
should generate.

But: the frequency tuning is a bit stiff/non-responsive and the tape
which is used in the oven is a bit old. Fixing this unit seems like a
nice winter-project ;-)

Is there anyone on the list who knows where to find the Sulzer
manuals (preferably as PDF)? As it is basically a Sulzer 2.5 / Sulzer
5.0.

Thank you, best regards, Jeroen

Hi,

Has anybody in UK noticed ebay item #140845930763 ? It reminds me the old Sulzer units, but longer.

Ignacio, EB4APL
