     do you and or your friends happen to have any old vacuum
tubes for sale,Robert, it looks like we both got snagged by the 'reply to list' setting.  No, I neither have nor know of availability of any of the models you listed.  My collection is primarily Tek.  Best of luck.
I do not wish to sell any of my tube stock at this time.

I don't at all mind being asked but my reply was directed to "free2beme953572002" (man I just LOVE trying to 'talk' to someone behind one of those nicknames) who asked for some 184A information.  I take the messages as email and forgot that this list is set to send everything back to everybody.  Perhaps Mr. Moderator (is that Tom Leedy?) would consider setting it the other way, as it is on the Tek list?  Most folks are smart enough to figure out whether a reply should be public or private.

End of two-cent rant,
Fred

Just bought an HP-184A scope today at the monthly Livermore 
Electronics Flea Market. 
Plus, a Tektronix 7704A mainframe scope....$ 15.00 !Checked it at 
home.The readout does work.In decent,good condition.A keeper.
Used my 7000 series plug-ins.
OOOPs ! Am I allowed to say "Tektronix"?
Has 2 plug-ins; a 1809 4 channel, 100 MHZ vertical. And an 1825A
timebase and H amp.The mainframe is a storage type.
Couldn't pass it up for $ 20.00.
Now, for the interesting part:No trace, but a glowing screen.
Beamfinder is useless.No spot. Just the screen glowing.
Tried BAMA for the service manual.Not in there.
Next, will try the mil site.
Stand by for a service manual request.
Just to let you all know what can be had, at the right price(s).

Re: Digest Number 58

#143

Walter,

I looked up your HP part number, 1884-0019, in my copy of the FedLog (Federal Logistics) database.

This is one of the first times it hasn't shown ANY equivalent part numbers and other manufacturers.

But it did have some technical descriptive data, which I'll paste below, in case it might be helpful.

Good luck!

Well, looking at this here manual, there is a RUN/TEST switch (A1S1).
The test switch is A1S2 ( 6 pin DIP sw) .  You need to set the COAX/OPT
switch (A1s5) TO coax... finally, you have to set the rate.  The test
switches A1S2 should be in the OFF position BTW.

What else?

Subject: [hp_agilent_equipment] Information on 37203A HP-IB Extenders

I've recently tried to use a pair of old 37203A HP-IB Extenders to extend the distance of several IEEE-488 instruments from the controller.? I don't have a manual on hand, but I thought the units should be fairly straightforward to use.? I set the "controller end" as Master and the "instrument end" of the link as "Slave," the rates at the same setting (Normal), and connected the power and -488 instruments.? Although I can see a series of negative-going pulses on the coaxial interconnecting cable, I can't seem to get communications between the controller and the instruments.? The length of the cable is about 150 meters.

Can anyone give me any guidance for their operation?? There are a few "mystery switches" inside the units along with a jumper printed wiring board -- I left all these as they were.? Any help would be sincerely appreciated.

Re: Digest Number 50

#133

Ian,

In the HP 8558B service manual, it looks like those switches are just assemblies of many different HP part numbers. I could be wrong. I've never looked at an 8558B. But I didn't notice a part number for an entire rotary switch assembly, except "Front Switch Assembly (Mechanical Parts)", HP part number 08558-60100, which includes all of the mechanical parts for the entire front panel switch(es) assembly.

Your BEST bet is probably to find an 8558B "parts unit" to get the parts from. You can probably find one on , eventually. Note that you can put an "auto-search" on eBay, so you'd be automatically emailed whenever anything matching your search came up for auction. Just go to "My Ebay", then "Favorites".

Darn! I just searched ebay, for "8558B", and then clicked on "Show Completed items", and it looks like an 8558B Front Panel Switch Assembly sold on Dec 15th, for $57.55. Maybe you could contact the buyer and see if you can get some parts from it, or maybe just get all the rest of it after he gets what he needs. You can go to  and then click on the winning bidder's ID (kcands). You could also contact the seller, similarly, to see if they might have more of them, or the parts you need. (They are a test equipment dealer in Wyoming.)

Also, you could try asking Walter, at Sphere Research, at:

But, if you do need any HP part numbers for individual switch parts, such as rotor/contact assemblies, shafts, or whatever, I can look them up for you. You would need to be very specific about the locations of the parts, since the rotary switches' parts are not all interchangable.

I also have the full service manual available (362 pages in two manuals), on CD, at:

Good luck!

Regards,

Tom Gootee
