I’ve just been repairing a TLA714 and the primary HD was bad. So this
is something I’d be interested in

?Dear Forum,

I have an old Tek TLA700 Logic Analyzer complete with software disks:
Application V 3.2 - 063-3022-04 ( 2 x CDRom ) Controller BIOS
1.00.14 for TLA704/711 - 063-2895-02 (1.44 Floppy)
W98 Boot Floppy - 063-3418-00 (1.44 Floppy)

If there is any interst in this, I'd be happy to zip them and submit
the files but where?

(I know there is a Logic Analyzer group but very few posts there)

Cheers

I'm a newbie who joined this group recently and discovered the overwhelming
interest in Peter Keller's book. I'm curious about what appears to be the
"bible" of CRTs, but I missed the boat on ordering.



So I logged on to my local public library branch and was able to request a
copy from the UC San Diego Library. I suggest that if others would like to
"try before you buy" you might consider heading to your local library to
see
if they can find a copy for you.

40 years ago I worked for a company that used pins similar to the ones Tek used.
They were filled with a similar material. They came on a flexible 1/4" mylar ribbon
for automatic insertion into a PCB.

I have seen something similar on GRiD laptops from the early to mid-80s, used for extra low-profile socket mountings on the CPU and FPU, for example. The original strips had a seal or gasket just like the Tek sockets. I was unable to find modern equivalents with the seal/gasket. I ended up ordering several strips of Advanced Interconnections Peel-A-Way sockets, but my sources for those have subsequently dried up.

Jean-Paul,

I will post photos shortly to the "Sick 2365A" album (/g/TekScopes/photos?p=created,,,20,2,20,0&jump=1)

I have the service manuals from TekWiki, which purport to be from 1974, have not effective or discontinued serial number ranges in the part lists, but do have two MCI pages (also from 1974).

Yes, I have come to the same conclusion as you about scopes, especially the large, non-portable sort, on eBay. Out of three such scopes I have bought, one was a complete loss, with the CRT shattered in shipping (thankfully I got a refund and return shipping label on that), and the other two are yet to be determined. The prices for all three, however, were right (each less than $100, shipping included), so it's hard (not impossible) to go too far wrong.

The reason I bought this scope was to expand my technical skills by fixing it (and just to have a 7000 mainframe scope, and a storage scope), so it's money and time well spent. If I were just trying to get a working scope to use for other things, then this would be a real waste. Aside from being a storage scope, the 7623A is inferior every portable scope that I already own. All of those scopes are working (and various kinds of rough handling, either in shipping, or by the original owners), and are my preferred bench scopes. This is really just a toy, at least until or unless I get a nice plug-in (e.g. a 7CT1N or one of the spectrum analyzer plug-ins).

Roger,

It's always good to be reminded of what I allegedly know (but may not, in the moment, recall). I had read about the color coding, but I'm not sure it helps much in this instance. My real concern was both getting the cables connected in the right places and orientations, and getting all the cables connected again.

I did notice that the case of the C811 seemed to bridge two "ground planes," and I added a jumper wire to do the same. I'm not sure it's of adequate current rating: it's single strand copper AWG 22 or 24, the spool is unmarked, but it's heavier than the AWG 26 that I normally use for breadboarding. I could easily add a second or third jumper if necessary.

It has occurred to me, after looking at the picture of the original CRT malfunction, and thinking about what would cause the current malfunction, that one of the horizontal deflection plates might be loose or disconnected, and that now both may be loose, or otherwise malfunctioning. After I get the power rails sorted this may be my second avenue of investigation.

Hi Dave,
These are the ones I use with their corresponding DIgiKey and Mouser part numbers:
Mill-Max Part Numbers
917-93-103-41-005000 CONN TRANSIST TO-5 3POS GOLD
0552-2-15-01-11-27-10-0 CONN PIN RCPT .015-.020 SOLDER
0552-2-15-15-11-27-10-0 CONN PIN RCPT .015-.020 SOLDER
All three of these are still available from DigiKey.
Mouser Part Numbers
575-055220 Mill-Max 0.015-.022” pin, 0.170” deep, for small transistors & small in-line pkgs.
575-0293015 Mill-Max 0.022-.034” pin, 0.170” deep, for TO-66 transistors
575-031400 Mill-Max 0.032-.046” pin, 0.236” deep, for TO-3 transistors & large in-line pkgs.
Only two are available now from Mouser.

Subject: [TekScopes] PCB sockets for plug-in xtors/etc.
Is there a resource for the sockets that are soldered into the PCB boards in scopes with plug-in transistors, ICs, diodes, etc.?
