Sorry about that, Mel.? Let me try filing down the epoxied bowed connector first.?
Thanks.

That would be fine. The only other part that is difficult to test for me is the tripler module with the hv lead. If you like you can include that also. Let me know the cost and method of payment you prefer.

I'm perfectly sure it will cause "some oddities" - I don't dispute that. I'm just very wary about winding that variac up more when the display is already brighter than IMO it should be (although I have only my limited experience with Telequipment analog storage scopes to go by which may be of no help at all here).

Hi all,

I'm really not very familiar at all with these exotic beasts. I'm powering up
a 466 (early version) slowly from a variac (they used a linear supply on
these) and at about one-half mains voltage I'm seeing a green glow on the
screen and that's all. I would guess by time I get to full mains this glow is
going to be *extremely* bright and that can't be right (the intensity control
doesn't make any difference, btw). What should I expect to see when powering
up a 466? It's been laying around for many years without being powered up at
all. I'm not giving it any input at this stage for obvs reasons; just want to
check it's not a junker before spending money on it.

cheers.

I would think that using a variac a1/2 voltage would cause some oddities. Other more experienced members will weigh in im sure.

Just use a different email address if you do not want this one shared.
They are free and nobody else needs to be bothered to change anything
and you do not have to rely on anyone else to keep your privacy.
You can even set up forwarding so you don't need to check another inbox.

All this is ridiculous. It's a public forum.
Don't get me wrong, I support the GDPR in principle, but common sense
still applies.

Hi Mel,
Yes, I did. I have been comparing it to what I already have and the documentation on the rigid and flexible extenders. It seems that it will do the job with a bit of fettling. My rigid extender is missing the plastic sides on the DUT-end connector and the tails that are soldered to the PCB are quite short. I think the sides are there to prevent damage. The longer tails on the connector that you sent me can, I think, be shortened.
I would like to reimburse you for the postage and pay you for the connector. Would ?10 be acceptable? If you let me know your PayPal account, or BACS details, I will get the money to you asap.
Many Thanks, Colin.

Hi Colin,

Have you received the connector yet?

Cheers,
Mel

Jim,

I haven’t receive your address yet - do you still want this connector?

Cheers,

Hi Chris,,

As the HT module is quite a bit heavier than just the transformer, I propose removing the Tx and sending it on it’s own. The problem arises if it’s not just the transformer that’ll faulty . . .

After various private exchanges, it seems I am describing the way it should work, rather than the way it does work. In a properly implemented system of this kind, the emails should come as 'from groups.io on behalf of Esmond Pitt' without my own email address being visible. See for example eBay grrr.

This is a matter not for group members to address via a policy, but for groups.io to implement via their mechanisms, with some urgency. It's not hard. They are leaking confidential information all over the place, including with this post

I see your email as part of the list server email I received.

Is there some way you can be anonymous? With BCC?

Thanks EricJ, I should clarify that I am referring to the CC: list, if indeed there is one. More probably it is a BCC:

EJP

Actually Esmond I am quite readily able to see your email address. You are with bigpond.

Can I point out that the email addresses that are provided in the mail headers are only those of people who receive group emails, not of the entire group. So for example nobody could use them to contact me, as I don't. You would have to use the Web interface and select the Private option when replying, and when you do so you don't get to see my email, and I don't get to see yours.

Yet another reason to use the Web interface ;-)

Panic over. It turns out I had the A Intensity control turned way down, and must have turned it even further down the other day. I never knew what the hell it was for actually, or B Intensity either. I do now :-| I now have them both set the same and the intensity from 7L5 and 7A18A is the same.

Thanks again for the assistance.

Hi,

I sent the following to the list a while back and didn't hear anything,
so I'm trying again, just in case. :-)



Having acquired a couple of panel-less X-Y scopes, I'd like to obtain
the one-piece metal cabinet which appears to be a standard size across
the Tek range.

About 5" x 8 1/4" x 16 3/4", I believe it is referred to as the Case or
Cabinet Assembly, part numbers 1700F00 or 1700F02 for the 17xx range.

Even better would be the 602 part, 390-0018-01.

Also looking for 602 knob, 366-0392-01.

I thought I'd check with the list first to see if someone had a spare
cabinet. Otherwise I'll have to raid surplus stores.

Related: Does anyone need (clean, but currently untested) 1720 boards or
spare parts? Details or tests on request...

Thanks in advance

Hello All

I'm a new member and have several scopes.
Current project is a 7313.
I got the regulator board working and finally got a vertical to show on the scope. I cannot get it to put out a horizontal signal.

Currently working on triggering circuit which does not work correctly., no output from the board, good input.
Does anyone have an extra dual base time plug in for this unit??
I think several of the ICs are not working in the triggering unit, any suggestions??

My initial impression when I first read the original message was that this was a solution in search of a problem. But I kept quiet, thinking perhaps there had been some incident that prompted this new policy. After reading the ensuing comments I found such was not the case, and further that most if not all of the 20+ respondants to the original posting opined that this new policy was both unnecessary and ill-advised.

"Becoming a member of TekScopes does not give a member permission to
contact another member outside of TekScopes without prior permission."

I am a member of a sizable number of support groups such as TekScopes, and none of them have such a philosophy that I am aware of and certainly none that have an expressed policy comparable to this. In fact many of the groups I belong to have a "Send Private Message" link to facilitate private messaging between member. Asking permission to speak to another member of a support group runs contrary to the basic concept of a support group, which is the free sharing of information and ideas.

This new policy is bordering on a Catch-22 - very much like "Before you can send me a private message, you must first send me a private message asking permission to send me a private message". Except that we must first send a public message to the entire group asking permission to send you a private message, thereby burdening the system with messages which have no relevance to anyone but the two affected members, and burdening everyone else with reading superfluous messages that are meaningless to them. As already mentioned, this is "Through the Looking Glass" logic.

So add me to the list of respondents who feel that this new policy was both unnecessary and ill-advised. But Dennis is the group owner, he has the conch, and he can make any rules he pleases, regardless of whether they are needed or supported by the membership.

Note: any member of this group who wishes to contact me privately may do so without prior permission

Thanks for your help.

1. The cursor is displayed normally with Display A+B turned on, and is at the same level as the spectrum display. Ditto when either A or B is displayed by itself.

2. With all digital storage turned off, so all you see is the cursor, the cursor is considerably brighter, but still not as bright as when the adjacent 7A18A is selected. I don't know what 'cursor knob becomes baseline clipper' means, but I can see that twiddling the baseline clipper knob changes where the cursor starts displaying from in the vertical axis.

3. Selecting a timebase plugin in the B compartment causes a considerably brighter (but of course incoherent) display, becoming visible at 11 o'clock and usable at 12 o'clock of the intensity control, instead of 3 o'clock when the 7AL5 is selected for B. The 7A18A is usable from between 10-11 o'clock.

4 Selecting Display A or B has no effect on brightness. Selecting both A+B is slightly brighter than either A or B by itself, but there's not much in it.

5. You didn't ask, but the averaged display below the baseline clipper line is the same brightness as the non-averaged display above it.
