Re: [time-nuts] Z3801A's

 My question is this... What is the current market value on working  and

tested Z3801A's?

Feed Z3801A to ebay and see what you find.

I see one at $1K, and 2 with power supply and antenna and cables at $480 and
$499.  (Read the fine print, YMMV...)

On the other hand, ebay has a Thunderbolt for $250.  There was one for $110 a
short while ago.

So my estimate for a Z3801A is ballpark of $250.  Maybe more if you are
willing to wait longer, less if you need to unload them quickly.


Does anybody know what "Z3801A has been upgraded by us, which the feature is
the same as 58503A." really means?

I bougth one, and it seems like they have replaced the firmware with the
one from 58503A. When sending *IDN to it, it responds with HP 58503A.

Kind of scratching my head here.
I have a 3801, great box.
But I also have to say that since it can't run lady heather I do not see
the value epay wants. Before everything spun up as they always do the 3801
was a $200 box and slightly less. I do not know why but I purchased mine on
epay and I want to say $175.
So if you have to have one then $500s fine, but it breaks my simple logic
in value.
If I had $200 I would certainly be considering the Tbolt.
What would I pay $75, since its a backup that I have lived 10 years without.
Just my crazy way of thinking.

To anyone in the Minneapolis area:

Collected a lot of stuff from eBay during the last decade, to keep
me busy in retirement. Turned out that need never arose. Now I can't
afford to keep an 8x8 storage locker anymore, so it must be empty
by the end of this month.

There are many rack-mount time code generators, most by Datum. They're
1, 2, and 3 rack units high. All have 5 and +/- 12 or 15 VDC compact
power supplies. The 3 and 5U units have 1 MHz crystals in ovens. All
have 9 digit led displays, and all speak IRIG. Thumbwheels are used
to preset the digits. None have GPS receivers.

There are time instruments by HP, as well as Tek scopes and other fine
old vacuum tube items.

All of what's in the locker is free for pickup at 6200 W Old Shakopee
Road in Bloomington, MN. Things that are not free include a pair of
Z3801As with HP cone antennas and 50 feet of RG8U cable and a Ratelco
48 VDC positive ground power supply. There's a 2 KVA sine wave Liebert
computer UPS that requires eight 12V batteries, as large as you like.

Then there's three HP 3335 synthesizers (200 Hz to 80 MHz) that I need
to test. Two of them work, IIRC. One has Telco outputs.

Pictures available from bill@iaxs.net, or call 952 835-6840.
