The links are definitely new. I was looking for some of these documents

First of all it was not just a list before. At the bottom of the document was a text saying that I would send
any of these document by email on request. The reasons for having it like that was primarily limited space
on the server but also I was curious about how many people wanted them.

Secondly the documents were all made with Acrobat 9. And yes they are password protected but not to open
just to change. The reason for that is that I want to preserve the watermarks to make it a little more unlikely
that the document will show up for sale on eBay which has happened before with "Troubleshooting Your Oscilloscope" which was the first document I posted and it was unprotected without watermarks.

Hakan,-

I understand your motives, but even though the "open" password was not set, the encryption was preventing opening of the file, at least on older readers.

PDF locking and security have always been a bit of a joke. I posted one way to remove your security earlier. This website: http://www.pdfunlock.com/ removes all protections as well. There are numerous paid software packages that will remove the open password, cracking even 256 bit AES encryption (although that may take days on a home computer).

In short, the old adage "a padlock only keeps out the honest man" applies to PDF security as well.

Hey Håkan,

The Chrome PDF viewer is unable to cope with these PDFs, as is iBooks.
By locking the files down this way, you essentially force their unlocking
and re-hosting, because as-is, they're unreadable to a large fraction of
the devices people use.
This probably goes the opposite to what you intended, but there you are.

PS: many thanks for all the docs and help you've provided.

All you need is a known news server to point your reader to. ISPs
got in the middle as a service, but they're not necessary. The
original service ran point-to-point over phone lines.

As an experiment, I wouldn't think it would be too hard to direct
the current mail feed into a news feed.

The only downside of a newsgroup is that anyone can get the
feed and publish trash. I stopped reading a number of
groups that I followed for years because the signal/noise
ratio got so poor.

A moderated group might work, although the volume on this
list might be a bit high for that.

@Hakan

Thanks for storing those manuals and I have no plans on selling them .. My plans right now are to right down each part number for the Tek 2213 &2215 scope in each parts kits in order to help everyone else out .
I know 1 transistor is a custom made part for tek scopes ..Oh is there any other parts kits ???


Like this one
Tek Part# 151-0852-00
50v,150ma,200mw Inverter
The part I cam up with is a
SJE6447 part

Contrary to popular belief news server is not required to be from one's ISP :)
Or even from the same country... And one is not legally required to buy
anything but Internet connectivity from an ISP...

There are many free and almost free news servers anybody can use.

And BTW many interesting people are lurking there that you won't meet at any
stupid forums. Really interesting people, well worth listening to and
interact with. Like almost all those guys who wrote or contributed to the
last AoE including Win Hill himself. Just read sci.electronics.design for a
day or two and you will find 'em all... BTW, there was 402079 messages in
just sci.electronics.design on Eternal September. It is four hundred
thousands. In one newsgroup alone. Free for all and not bound to any
provider, state, continent or whatever else.

It is moderated but only very loosely, generally the approval process to
become a member goes through the moderator but after that posts are
apparently not reviewed ..if it were rigorously moderated this thread
would have been killed long ago....

Since 2008 we have flogged this horse rigorously at least three times
...all talk ...no action

Reminds me about the story of the Game Warden and Zeke.

GW hears that Zeke has been using dynamite to "catch" fish. GW goes down
to the ramp early one morning to confront Zeke.

Zeke denies the allegation and invites GW to go fishing with him. The GW
agrees and they row out to the middle of the lake.

At this point Zeke reaches into his tackle box, finds a stick of
dynamite, lights it and hands it to the GW with the admonishment..
" you going to talk or go fishing?"

I think you get the idea..if you think news groups are the way to go ,
start one and see what happens... talk is cheap

Something you guys may be forgetting or may just not know, news articles
(for lack of a better term) on NNTP servers expire after a preset number
of days. Binaries are usually gone after 3-5 days, normal posts are
typically gone after 7. Unless you own/control the server this is
somewhat standard, and by expired I mean deleted.

Q933, Q935, Q940, Q942 in 2213 and 2215






I am missing one, which is (119-3511-00 Diode/resistor network) and I can't find any information about it ..
The 151-0852-00 transistor was custom made by On Semiconductors(Will try to find alternative if possible)...

I will post pdf later with tek part# to actual part for repair and can someone help with the diode/resistor network and custom transistor replacement ??


Thanks

It is true but it depends on the particular server. Storage is dirt cheap
these days and usenet traffic is not growing any more so most of serious
servers keep articles for several months at very least. I remember old days
when 1Gbyte hard drive was something rare and very expensive and usenet was
growing like being on good yeast so we hit a limit where articles were
coming in faster than we could expire them :)

Now it is different so there is no problems setting INN with several months
worth of articles. Binary groups are not all that popular either and usenet
is actually not very good for this, web/ftp sites are better.

There is another phenomena -- Internet has multiple usenet archivers setup
for different purposes but those do exist so nothing is lost. Archivers do
not all belong to a single entity so the entire usenet is mirrored and
archived multiple times in different places. Simple internet search easily
brings up my own usenet posts made 10 years ago and those come from multiple
sources.

News server is just a mechanism for providing quick interactive access to
relatively recent articles, say a month worth. Usenet on the other hand is
not just NNTP/NNRP servers; it is way more than that and it is not owned or
controlled by anybody. It does not rely on any particular company and will
survive heavy losses. _ANY_ modern whizbang shiny flashy-blinky forum full
of javascript and whatever else is only alive when its owner is still
kicking. When Yahoo had gone belly up _EVERYTHING_ will be lost forever in a
blink of an eye.

And please don't think it would never happen. Does anybody here remember
Vera Lynn^W^We.g. AOL "Virtual Cities" or whatever it's been called? There
were many very good electronic-related and other useful resources there,
kinda like Yahoo. Everything went "Poof!" one night when their management
decided it was not boosting their revenue so all expenses on that useless
thing had to be axed. It was all here one night and vanished next morning.
They didn't even give content owners a chance to retrieve whatever they had
there and move it somewhere -- everything had been wiped out.

Remember, the bigger they are the harder they fall...

Re: WTB 7A18A pop-out shaft coupling

Is it aluminium, I would guess about 3/4" long, 1/4" diameter with a
1/8" bore on one end, an 0.081" ( #46 drill bit) bore on the other and
two set screws?

If so, it would be easy to make a couple on the lathe.
