Greetings,

I have searched the internet and all the manual providers I could think of
without any luck.

I went to use my little Radio Shack (Micronta) 22-165 DMM on AC line and
was certain it would be just fine at 120 VAC, and it was - but I really
wanted to check it’s specs.

I’m pretty good at keeping all my manuals and knowing where they are, but
I failed this time. The little manual was not where it should be and
nowhere else to be found.

Does anyone have a user's manual for this little meter they would kindly
scan to PDF and share with me?

Thanks for use of our bandwidth and your consideration.

Regards,

Ken

About the status code my version of Common Design Catalog says it means:
"An item that is no longer produced or purchased and which has no replacement".
It doesn't say if it was ever used or not.

And I was so close. I pored over parts lists for the 4025, 4023, 4014, 4006,
and T4002, but did not try the 4002A.
I checked the P/N's again because there was also a circuit board P/N listed using
these P/N's which I assumed was for 4002A but it turned out it (670-1449-00)
was for T4002 B050000 & above so I have to revise my previous reply.

Re: Discord server for Tek & HPAK lists

Sounds great. I am already on Discord, so will add this one in.
Thanks!
Randy.


Ps....once I have time, will post some pics of my 7633 with now non-working

Hi all,
since a few people voiced interest in this, I set up a Discord server
for the Tek and HPAK lists. Before joining please read the below.

Discord is a free program (with a paid tier as well which you don't
need) that allows you to chat in real time using text chat, images and
file attachments, as well as voice chat and real-time screen-sharing
video streams. It works on computers as well as on mobile phones
(computers). Each community has its own server (you can also say each
community has "a discord" or "a guild"). Each server contains several
separate text channels which contain logs of past conversations. The
channels are usually dedicated to one topic each.

There's a few things to mention.

1. This does not replace either list. It's not "official" in any way.
Moderators of the Tek and HPAK lists are not moderators on the Discord
(as of now).

2. There are channels for HPAK and Tek as well as other topical
channels and an off-topic "general" channel. There's a channel for
"other testing equipment" as well as a general electronics channel.
Other channels can be added by me if there's ever a need, it's not
really limited. If you see a need let me know.

3. This is meant for real-time chat as well as general chat, getting
to know each other more on a personal level, checking in on each other
if anyone is in bad health, talking in real time when trying to work
out technical issues, do presentations, video streams, etc. You can
put Discord on your smart phone and beam out its camera to other users
in real time to show them around your collection or a circuit, and
that's very useful.

4. The rules are described when you first join the server and you have
to accept them to be able to take part. Some channels have extra rules
in the topic. I will make up other rules as I go. I will likely
arbitrate things that are not described in the rules and might decide
in contradiction to the rules. I will probably bring in others to help
at some point. Anyone who doesn't like the rules can leave. The rules
will be different than on the mailing lists. Anyone who acts badly
will be made to kneel on vintage NOS tunnel diodes for 6 hours right
after being flogged with 900mm triax cables. This is not an invitation
to act badly (you know who you are). I would love to say that everyone
is welcome but obviously some people will find ways to make themselves
unwelcome, don't be that guy.

5. Please use the same name / user ID as on the mailing lists, so we
know who's who - it'll make things much easier. Please use general
sense and always prefer to keep a friendly (not just civil, but
explicitly friendly) conversation rather than a "technically anally
correct" or "i am logically more in the right" conversation. Point 4
applies. Don't spam, don't flood, try not to use enter as punctuation,
don't post walls of text.

You can join the server using the following link, which will expire in
7 days. This is to prevent spam bots from joining. If you want to join
past those 7 days, email me off list and I'll send you a new link.

It's best of you first install the Discord desktop application on your
computer or phone, and then enter the link there by copy-pasting or
typing it in. You can also use Discord from the browser, but that's
less optimal, because you won't be able to know if someone's talking
to you when you don't have the Discord tab open, and Discord is
primarily about immediate contact, which is then lost.

Thank you, Håkan - you are an encyclopedic asset to this group.

So they were actually used! All these years I have misunderstood what the STATUS column means in the Common Design Parts Catalog. So “DL” (Deleted) is both parts that never got into a product *and* parts used in long-discontinued products… do I have it right?

And I was so close. I pored over parts lists for the 4025, 4023, 4014, 4006, and T4002, but did not try the 4002A. It was before my time and AFAIK I never saw one.
I will go back to the Northwest Vintage Radio Society member who has them, and tell him where they go.

Re: Repair question for Type D High-Gain Differential plug-in

Dave Wise
 

Daniel Koller, those tubes were selected and matched for grid bias at a given cathode current, and gain. The specs are in the "157" document in the Replaceable Parts Registry at w140.com . Just search for RPR.
You may have to build a test jig like Tek's.

According to the 1987 Common Design Parts book, all three are TMS4100 character generators. TMS (TI) 4116 and 4164 are 16 kbit and 64 kbit dynamic RAMs, respectively.

Perhaps used in (27xx) Spectrum analyzers?

Yellow book says TMS4100 (and deleted) on them, which would be a TI 4116 or 4164 or other memory. Maybe a Wilsonville product?

Ke-Fong LIn,

Thanks for setting up these scripts. I'm modifying them to create card edge connectors for some vintage HP interface cards. Probably do some extender cards too, once the footprints are in the library.

Much appreciated!

Re: More hard to find Tek parts, and a great EPROM programmer

My experiences with Sphere have been like the others who report good
experiences. I have bought slide rules as well as electronics. Shipping has
gotten very expensive, though I have discovered that you can save shipping
costs if you have an account with the shipper - particularly FedEx. I
shipped two large (two boxes about 20” cubes) with microscopes in them. Yes
- I overpack them having received broken microscopes because shippers did
not know how to pack them. Anyway, the recipient said to use his FedEx
account because it would save on shipping. Did it ever. I have shipped
boxes like that about the same distance and having the same weight and paid
well over $200 for both. The cost to the recipient for these two? $38. Now,
the pricing may depend on your shipping volume, but this was an account
number for a university. Personal accounts may not save you quite so much.
I’ve set up an account for myself and have a couple of more microscopes to
ship, so I’ll report back on how much it costs/saves.

I usually factor shipping cost in when purchasing something. I had an
unusual experience with an eBay seller. He offered to sell me the HP
counter I had looked at for $1.00 plus shipping. He is in Canada. He knew
what the shipping cost would be, but at a price of $1.00 for the item - no
customs. The shipping wound up being about $120, but $121 for that counter
was a good price. Even if he only got $1.00 for it, he got it out of his
“inventory” so I guess it was worth it to him. It was also one of the
best-packed pieces of test equipment I have received (noting that Sphere
does a great job also).

Sad to report otherwise! The only time I got a part, it cost me over the

A subsequent quote had to be rejected due to the ridiculous shipping
charges. There is still a part I would love to buy but I am sure it will be
another ridiculous shipping cost. So, it is a no go at the moment.
Sphere seems to be a great source for old TEK parts but as most people
have experienced, Canada Post seems like a money making machine for the
Canadian government, unlike the USPS.
My experience should not deter others but it was just that: A bad
experience!
