I too use Sugru, especially where the connector/wire ratio is very large
and many different sizes of heat shrink would otherwise be necessary to
build up a strain relief. I've not been able to make Sugru
reinforcements look good but the stuff works like a charm.

This is not only a free server it is an anonymous server. The user has
no obligation to identify himself. That is the reason why these servers
are so popular with trolls. And the very first nntp-server on the line
(in fact close to the end) tells you the injection point because these
troll-servers also suppress the injection-info.
 
It is easily possible that the routing to your server looks different
but not the injection point.

The injection point is: news.highwinds-media.com, a typical troll-server.

Guys and Gals!
 
You are feeding the troll simply by continuing the discussion.

Lots of replies, so this may have been suggested already

It is absurd to judge a troll solely for using a free server. I get a
very different path for the same post.

That's the best idea ever!

The pen spring was suggested but until I saw your photo I didn't think the
pen spring would work. You showed that a pen spring _is_ big enough to roll
onto the Apple cable becoming what I had called a strain relief but I don't
know what it's called because others said it's not a strain relief.
 
That picture is PERFECT for what I want to do, and is the best and cheapest
answer yet and it relieves the strain gradually which is another perfect
thing!
 
Now I have to root through the trash to find all those Bic click pens I've
thrown away over the years! LOL

It's about the right-hand side of the Path. You read a Path from right
to left. The right-hand side indicates (read: should indicate) the
origin server of the post.
 
The right-hand part of the Path is the same:

You:

In this particular case, a long part of the Path is the same. Normally
it's only one or two !-parts.
 
The rest of the Path shows how the post got from the origin to your
news server. Because Joerg and you use a different news server, that
part of the Path is different.
 
HTH.

Well, I have been using news.aioe.org and freenews.netfront.net for a
long time, and I'm certainly no troll. I simply do not like to pay and
my ISP does no longer provide nntp.
 
Thus I make nothing of using a free server.
 
If a name shifter uses always the same server, well, that's a clue, but
not definitive. Posting from there is not definitive.

Interesting, in that picture, the USB cable jacket is *already* compromised.

True, but for example aioe *is* used by a lot of trolls. Example: Our
resident nymshifter.

Huh? Aren't you using the pay-server News.Individual.[NET|DE]? :

That's your Path to me, i.e. we're both on News.Individual.[NET|DE].

Just thought I'd let you know, it is finally done. I had help too. Anyway :
 
Wired in substitute transformer for filament of CRT.
 
Replace Q 260 and modify to accept silicon.
 
Replace Q 233 & 243, silicon worked fine.
 
Bypassed variable vertical gain controls.
 
Cleaned output level switch and tub socket on calibrator.
 
Basic calibration of sweep and vertical gain.
 
Sounds easy eh ? It took some doing to figure it out and the modification for Q 260 was all wrong at first because I am not that familiar with working in a negative supply. But someone pointed out my mistake and one piece of quick math it was good to go.
 
Anyway, between "A Little Help From My Friends" here, on SED and the Tek Scopes group it is working pretty much perfectly. It might need a bit more calibration but I need to obtain a couple of things first. It is however, plenty usable right now.

Yeah, working with a negative supply is not intuitive to me. I usually walk away, have a cup of coffee, come back and then it's (sorta) clear.

I remember the first Fox body Mustangs had a custom sized tire and rim, and they were eventually discontinued by Michelin. IIRC, the rims had to be swapped out to standard GT rims.
