As an experiment, I bought an AIMS sine-wave inverter for the 105B
Quartz Oscillator. The inverter has a built-in transfer switch that is
supposed to allow the load to operate from the AC line and automatically
switch to battery/inverter should the AC power line fail.

Hi:
Let me second Chuck's comment on the noise. You can NOT have this inside any
living space.
I saw this based on running an HP 117 for some time in the garage but also have
one of the 115BR units.

There is a fist sized bag of silica gel sitting in an

Most units also have a little 24V Nicad pack.

Hello,
The setup is the following:
makenametype
level/attenuation
Tesla [?]T284 SWR
bridge
Rohde & Schwarz SMIQ 03Genera
My speculation on the xtal. So the question is what is the empty box on the
right that looks like paper is stuck in it.
Not that any of this matters as I am not a bidder.
It may just add additional challenge for whoever gets it.

I have one of those, only in light gray.
It works quite nicely, though it is obscenely loud!
It has a divider network that takes 100KHz from a
companion reference unit, and divides it down to 1KHz,

I have worked on these and the electronics is almost always working, or
easily repaired.
The mechanical can cause problems depending on how much "time" it has on
the clock mechanics.
No XTAL in these as the drive is external.
The case is hermetic and has dessicant inside.

Hi Mark,
If your Lucent KS unit does not come in soon let me know and I will still be
glad to lend you one of my units with power supply to play with. I have
offered this several times in the past but did not hear from you.

According to my -hp- catalogs it was available only in rack-mount form, not
in a cabinet. That suggests it was being marketed to a specific small group

Rare is indeed a relative term. I would certainly call it rare, but others
might not.
You likely would be the only person on your block who has one :)
In the picture of the innards you can see a number of fine old wet slug
tantalum
capacitors. One even appears to have goo leaking out of it.
what is the link ?
