Re: [time-nuts] Hello and HP-5370A question
Hello Randy, Thanks a lot for your message! Yes, the 5370A has 3 extra spaces. They're labelled Spare, Memory Option, and Service Aid. The 5370B apparently switched to higher-density EPROMs (the A uses 2708's), so it doesn't need the ROM board. There's also a 12-pin board near the fan for the oven oscillator option. Great!!!. So I have a full unit :-). Well, now is is _just_ a matter of repairing it... as I have got also a paper Service Manual in same deal, at least I have the tools to start on it. Anyway, if somebody in the list has a parts unit, please, contact me directly as I guess I will need some in a near future. Also, the 5370 and the 5345 really only share the input boards, and possibly the oscillator. Ok, it is not too much but, judging by other comments about failing input amps, it is nice to have some spares. Again, thanks a lot!. Now I need, besides repairing the unit, to learn about time measurements as, judging by the level I see on this List, I am just a beginner :-). I will check List archives and links.

Re: [time-nuts] New frequency standard, Mercury better than Cesium?
Hi all, Yes some TE is exempt. Not all batteries are, mercury cells were banned about 10 years ago. This was a great pity as they make great voltage references! Hg is allowed in lamps, lead in ceramics and Cd in light dependant resistors. I don't know who will enforce it, I can't see trading standards wandering around with an X-ray fluorescence tester! EMC has been around for a while and there are lots of non-compliant items for sale. Some are obviously non-compliant others fail under test. We make laboratory automation equipment that uses PC's for control, We take a unit for testing and it fails because of the PC. One failed with the PC running with just the power lead connected, no keyboard, mouse or monitor. The supplier said it was compliant because all the parts we CE marked! Sorry for the rant, but I feel better now.

Hi Chuck, yes, all test equipment is excempt from RoHS, until between 2009 - 2011. Europe is not sure how long they will keep this exemption in effect. There are so many legacy products that are vital to the industry and that will not be re-designed that I think the exemptions will continue beyond that. Doing Lead-free has many reliability issues, let me just mention shorts caused by tin-whiskers, and the problems of visually identifying a cold-solder joint... The assembly houses I have talked to hate doing lead free work for critical, expensive items. How much test equipment ends in a land fill? Probably not too much due to all of the gold used in it, the collectors' value etc. Also, who is going to test all the products for compliance? It's probably very easy to get away with not complying.

Re: [time-nuts] New frequency standard, Mercury better than Cesium?
Both cesium and rubidium is harder to come by, but ebay being what it is, it is no longer that hard if I really wanted to. I have always wondered where one actually get these things on a commerical basis. There are companies in the business of supplying that sort of thing. You just have to find them. It took me a few minutes with google to find Fisher Scientific. https://www1.fishersci.com/Coupon;jsessionid=E8gHglzLzW1nLscKcCAg1axhtmV2a7zfj 47fHzNtEPdHNCtzaM2x!-994379636?cid=1334gid=222808 $57 for 1g of Cesium. If you feed cesium to their search box, you get 100s of hits. (Many are different quantities of the same thing.) Or look at the ads along the right side of a google search.

RoHS also addresses this, the manufacturers have to take back old equipment and dispose of it properly. Actually, this is covered by a different set of rules in the EU called WEEE which requires manufacturers to take back either gear that they've sold, or sometimes other people's equipment that they're replacing. It actually went into effect last year (ahead of RoHS). And, lots of other countries and several US states are getting on the WEEE/RoHS bandwagon, so it's going to be a pretty universal set of requirements before too long.

Re: [time-nuts] caveat emptor: eBay tm seller warning
Christopher,
Back in January of this year I purchased a 5061A from Test Equipment
Surplus (Mr. Joon Kyong). It was defective and I sent it back,
expecting a prompt refund. However, no amount of begging and pleading
had any effect until I left negative feedback. He responded that very
day! I did eventually get most of my money back except for return
shipping, which was very expensive. I lost about $80.00 on the entire
transaction and ended up with nothing. I, too, will never purchase
anything from him again.

Although I have satisfactorily done business with him on eBay several
times, I got ripped off in my last transaction.
I recommend you do not do business with him. To substantiate this
recommendation, here's the story.
I bought an HP 5065A RUBIDIUM VAPOR FREQUENCY STANDARD, item
#7614062550, from the seller for $555 + s/h.The unit arrived in
great cosmetic shape but with a suspicious rattle. I popped the top
to find the physics package missing. The rattle was the bracket for the
package.
I was annoyed but unworried. The item was advertised with the
following guarantee:
This item is in good working condition and is guaranteed to work. If
you receive the item and it does not function, please let us know and we
will give you a full refund including shipping.
No physics package == not good working condition, right?
I contacted the seller, and he agreed to take the item back. He gave me
his FedEx number. Great, I'm thinking, I don't have a working 5065A,
but at least I'll get my money back and I don't even have to spot him
the return shipping.
It took me a few weeks to get the package back to him -- we had a baby
at that point -- but I sent it the week after we got back from the
hospital. I have confirmation that the item was received and signed
for.
I have yet to see my refund, even after many messages asking him to pay.
It's been long enough that PayPal won't do squat about it. Short of a
small claims action, which I am seriously considering, I am out $500.
('though I understand I may be able to get $200 back from eBay ...
haven't looked into this in detail yet.)

[time-nuts] manual 5370A
Hola Jose, Well, I have uploaded the 5370A manual of 42MB last October to David's site, and it seems to be still there: http://www.g8wrb.org/data/HP/ (circuit diagrams are stitched for plotting on A1/A0 plotter.) There's a picture on p. 252 (8-93) of this 'A' unit, 3 PCB spares can be seen, plus one additional space without a socket.

[time-nuts] eBay saga re: Test Equipment Surplus, eBay id jtsele, aka [EMAIL PROTECTED] aka Joon Kyong.
Hey 'nuts -- I got my money back today less a few dollars (!?!?!) and a ~$20 PayPal fee. I neglected to say when I related the sordid tale that I had initiated an eBay dispute on the item. It had absolutely no effect. The kicker seemingly was declaring that I would proceed with criminal and civil remedies. Anything over $400 is grand theft in California. I got messages off list from several others who had similar experiences with this seller. One used the eBay dispute process to get his money back; the other had to resort to the threat of involving the police. So, again, please be warned. Final lesson: if you pay someone through PayPal and you have an issue, watch the clock carefully. File a dispute preemptively, if you are close to the cut off. So, anyone got a *working* 5065A for sale? :-) Cheers, -- Christopher. p.s. I am certain that eBay item #330009365677 is the 5065A I returned. It is in great shape cosmetically, but it has no physics package. ___ time-nuts mailing list time-nuts@febo.com https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts
