Ditto; I thought it sounded familiar, but a quick search proved me wrong.??
My Z3801 was the most expensive piece of T&M gear I ever bought, and it's still running too, but it only gets used occasionally now.

Hi Tom,
I searched the time-nuts list but only message I found was someone asking about Z3804 back in 2009 and there was no reply. I may join the list to ask. Is febo hosted one the most active?

Re: 3458A Schaffner Mains Filter
Usually, they come apart by drilling a rivet, and melting the tar... Some are soldered together. Tar = Messy job. -Chuck Harris On Fri, 09 Sep 2022 09:40:36 -0700 "Matt Huszagh" <huszaghmatt@...> wrote: "Carsten Bormann" <cabocabo@...> writes:
But if you need to replace them, getting a new line filter is a bit
less of a waste of time. If you try to repair the line filter:
Definitely do *not* get a replacement cap that is again a clear
blob of hard epoxy; these will fail the same way some 20, 30 years
from now. Best get one with a plastic cup and some more ductile
plastic filling covering the capacitor coil. Kemet still sells metallized paper (MP) caps that appear to use the
same epoxy coating. Do we know that modern Schaffner filters have
opted for the film caps over the MP versions? Has anyone opened these
up?
Also, how simple is it to open up the line filter and just replace the
caps?

I just bought another Agilent 16702b.
The original SCSI drive has failed.? It was an IBM DPSS-309170 which is a 9GB Ultra160 68pin.?? ? There was an Agilent 16702-xxx part# sticker on the drive so I'm sure it was the original drive.?? It was set to SCSI ID 6 which seems to be the OEM value.
I'm trying to install onto a? replacement Fujitsu MXJ3367SC680600X which is a 36GB Ultra160 68pin.
I found it was necessary to install the "Force narrow:? 16 bit scsi" jumper (#7) on the Fujitsu? Odd verbiage as narrow is 8-bit.
More bizarrely the installer will only run if the drive is set to SCSI ID 0.????
If I set it to anything else (SEA in the BIOS shows I'm setting the correct ID) when the installer runs from CD I see "Scanning system for IO devices ... Querying disk device [id] reported a size of zero",?? Same as reported here:?
The drive seems to work perfectly.? I hooked it upto a PC with a Adaptec 2940UW controller and ran a block scan without issue (set to ID 6).
Anyone seen something similar?
Thanks
---
As an aside (in case it ever helps anyone else searching) when I did the install onto SCSI 0 I got a ton of errors of the form "Warning: utime of file: <path> failed.? Invalid argument (22)".? Sure enough the RTC on the board was showing 2088.? I reset it but next time it was showing the year 20135 ;-)? After taking half the machine apart I confirmed the 2325 lithium battery was reading 0.35V.????? Now I just need to wait for the replacement to arrive from Amazon, uncommon size.?? Hopefully this fixes the above issue.

Subject: [HP-Agilent-Keysight-equipment] HP Z3804A? Does anyone have information about HP Z3804A "Oscillator and Distribution Amplifier". It seems to have a GPS receiver and multiple 10MHz outputs but searching on internet doesn't return any datasheets or manuals. Only information I found is this product line was sold (probably to Symmetricom).

Re: HP 3580A Spectrum Analyzer - broken frequency display
Hi Marco, That's good you've removed the bezel without damage. Yes, the display part number is KCSC02-105, I can send you a PDF of the schematic and PCB, this also lists the display part number. If you want to email me directly my address is peter@.... Regards, Peter

OT WTK -Wanted to Know: Reliable sellers, and on-line lists.
Hi All:
Does anyone know any reliable on-line sellers, or on-line lists, for HP gear.?
I promised a student a scalar network analyzer (for some field data collection)... after a seller had offered me one.
But then, they sold part of it (the power meter), and said good-bye on the deal, when I didn't want the ancient (and very heavy) sweep gen that they were offering.
I'm kind of stuck now.
There is a Wiltron (that I fixed); but I need at least on more power sensor.
Does anyone have any leads?
Best regards.
Roy

Hello Eric,
I might be interested in the Wiltron signal generator. Could you give me some details ( price, pictures, actual condition, is the GPIB working, do you have some manuals available)?
You have listed earlier some other equipments ( HP 3488 mux and EIP counter). Are these still available? These might be also interested for me.
Thanks,
Gyorgy

Re: OT - AN/PRM-10 Numbers on name plate
The 06728 looks like a "CAGE" code (Commercial and Government Entity), which crosses to Airtronics International Corp.
The AF36 number is the USAF contract the unit was purchased under.
Hope this helps!

Re: 3458A Schaffner Mains Filter
I have just had two blow-ups in an 8514 and in an 8515. Nasty stink!
Does anyone know where to obtain replacements for the Schaffner mains sockets that mechanically fit?
The ones I see here in Europe are all too long. The chassis of the 851x is in the way.
