Re: HP 16500A,B,C parts, 16515/16A pair

Greg Bowne
 

I have been trying to rebuild a 16500C for a while now.. could use a mainboard and perhaps a new frame/case/chassis.. the one I have is damaged.? The PSU also has some issues too.? But I will take any 16500C parts that anyone has.. especially the motherboard/mainboard.

Thanks,
Greg Bowne

I figured how to swap a good monitor from a 16500A to a 16500C
after taking apart the A. No more dim view!

16500 Frame parts, odd screws, covers, strap, mainboard,
touchscreen bezel/front panel assy, 3 or 4 of those projecting back side protector feet,
power supply, card cage halves, floppy drives, blank filler card, fans --
are available cheap, (for a few days at least), via USPS from 78756 Austin TX.

All the frame parts interchange between A,B,C. Not sure about the power supply --
different part number even though looks same.

No bottom feet or boot discs though.

Extra plugin modules:
16515/16A 1000MHz state/timing plugin pair with 32 coax probes $75
16510A LA 25MHz-state/ 100MHz-timing with probe leads but can't spare any probe ends $10

Re: FS: HP8568b 1.5 Ghz Spectrum Analyzer with HP8444a Opt. 59 Tracking Generator

 

Hello Jose,

This seemed extremely interesting to me, as I have a (I guess) less
common 8444A with Option 058 (yes, it is not a typo; difference sems
to be it only goes to 1.3GHz) so perhaps I could use it with the
8566A... but I guess you wanted to write 8558, right?

Best regards,

JOSE
The 8444A opt.058 is almost the same as the opt. 059. Only, the output filter cuts earlier - nominally at 1.3 GHz. In effect it is very useable up to 1.5 GHz; the opt. 059 goes at least up to 1.6 GHz. Very little difference :-)

Good for any SA with 2.050 GHz 1st IF, of course.

Actually the same TG won't work with an 8566, not without some tinkering.
The first IF is 3.621 GHz in those, rather than 2 GHz as in the 8568 and
earlier models.

That's not to say it couldn't be done, but you will need a new LO if nothing
else.

Jose ,
You can use it with your 8566a, I use it with my 8568A. It will only
work for the low band for you but it is still useful. Its not good for
RBW<10kHz but ok. You might try replacing the free running 500MHz
oscillator with a crystal locked one for smaller RBWs.

332A balance pots

 

Hi guys. Was wondering if anyone knew of a new/NOS source for the dual concentric balance pots in these things? After restoring my 332A it works fantastically except that I would like to put a new balance pot in her.

FS: HP8568b 1.5 Ghz Spectrum Analyzer with HP8444a Opt. 59 Tracking Generator

Howard Ashcraft
 

I have an HP8568b that is in very nice shape electrically and cosmetically.
I purchased it from a professional calibration lab that was upgrading its
equipment and was last calibrated by them in October of 2006. Since then,
it has been in an equipment rack in my workshop. The HP8444a tracking
generator is less common Option 59 that works with the 8568b. It is in good
shape electrically, but there are a few scratches on the front panel that
were probably made when someone removed stickers. I can send photographs if
you are interested. Price is $1,000 for the pair (I am not interested in
selling the tracking generator separately), plus packaging, shipping and
insurance from Alameda, California. Better yet, if you are local you can
save the cost and pick it up by arrangement and I will throw in a GPIB
cable.

Please reply off list.

Re: HP 5326 counter repair question

Antonio
 

Fred,

I have printed page 8-39 of the manual to see if I can help you.
I think the most significant zeros being present in your Nixies have nothing to do with the -5V. It is probably caused by some logic fail in the display module.
The schematic have two major sections: input switching and buffer amp. Input switching is done by relays K1 to K6 controlled by transistors Q1 to Q6.
If I understand correctly -5V is read by a multimeter (assuming the (-) probe of your multimeter is on the black terminal), connected at the DVM input terminals.
Now let's start some tests:
Note that there is no -5V supply entering this board so their presence at the input can be a misleading symptom. What happens if you short the DVM input terminals?
The first question is if -5V is present at ANY position of the DVM range (10V, 100V, 1000V) switch and the READ and READ B of function switch.
If it is always present, I would simply pull out A12 and see if the display zeroes. If the display read near zero at this condition, the V to F (A13 board) and the remaining circuits can be considered good and the cause is really A12.
First check continuity at pins 13 and 14 of the A12 card edge slot. This connection is the feedback path of the buffer and is completed at A13 (see schematic). If wrong it can lead to imbalance in the buffer stage and cause strange behavior.
If O.K., check diodes CR2 and CR3. Short gate of FET Q7A to signal earth and put A12 back. The display should zero if buffer amp is operating correctly. If it zeroes search for some input-switching leak putting -5V in the input buffer. If the zero condition cannot be obtained shorting input gate Q7A to earth, the opamp is
the probable cause (assuming all transistors measure good).
In my case both Q7 and U1 were bad. Putting a new LM301A and substituting my burnt FETs by near identical IDSS discrete FETs restored the operation. The zero adjust trimmer R31, however, was unable to zero the instrument because of FET imbalance.
Anyone knows about a reliable source of dual JFETs?

Hope this can help you to troubleshoot you 5326B. Good luck!

Antonio Falcao

I'm restoring this counter but there is about -5V on the input terminals from the DVM and the counter gives that value on the nixies I suspected the input-FET. A duall FET but that tested OK . Second problem is that the nixies all are on, while the nixies that are zero before the decimal point should go out except for 1. Maby this is related. I can not trace back the origin of the -5V. All transistors and FET's in that "line" are OK. Any one a suggestion. I'm now trying to fix this for a few weeks and today have spent a few hours reading in the manual trying to sort it out.

8405A Probe Tips

billw77aaz
 

My 8405A, probably like 99.9% of available units, was missing the probe tips and I presume they have not been available from HP for decades.

I've kluged a couple of different things. Anyone find a source, or figure out how to manufacture proper probe tips?

Very OT: Help on Staten Island, NY.

J. Forster
 

Sorry for the OT post, but a friened is in need of a small favor that has
to be done in person on Staten Island, NY.

Background: My friend did a lot of data base work for a politician running
for NYC City Council on Staten Island and the candidate refuses to pay her
for her work. Repeated efforts to collect have been ignored, as have
complaints to the appropriate NYC authorities. It has come down to filing
a law suit.

The favor: Attempts to get the forms for filing a lawsuit pro se (w/o a
lawyer) have to be PICKED UP in person at the courthouse, 527 Castleton
Ave., Staten Island, NY 10304. What is needed is the form to file a suit
pro se and the instructions that go with it.

If anybody is willing to pick up the form and instructions and mail them
to me, it'd be most appreciated. Please contact me off-list.

TIA,
-John

Re: HP 8662A parts needed

J. Forster
 

Can't help you with parts, but NiCds have Potassium Hydroxide in them, a
base, not an acid. You use a mild acid like vinager to clean it up.

-John

=====================

Hi Group,
I've nearly completed rebuilding a 8662A that was in a horrible state. The
nicd pack had exploded long ago and the fan had helped the corrosion
spread all around. As well as that it was caked with dust worse than any
instrument i've seen. Anyway after stripping, washing (!) and fixing
corrosion related issues it basically works. The only thing which is
beyond repair is the front-left sweep panel, the battery acid seems to
have eaten the lettering of the panel.

So is there anyone out there who has a donor unit with a this panel? I'd
even be happy with fairly average one.

Also it seems to have some failed LED modules, does anyone know if they
are still available? Corrosion may have killed these aswell. I think they
are also used in the 8640B. HP part nm. 1990-0330

182C CRT access

 

Hello all,

I can't figure out the steps needed to access the front glass plate of
the CRT on a 182C display. I need to clean all the plastic covers AND
the CRT front plate.
I guess I need to remove the front plate of the instrument, but how?
Can anyone tell me the needed steps?
Thanks in advance and best regards
