Re: Tek Probe Cables free to a good home

 

Hi Jack,
Thanks, I didn't have much luck when I googled those part numbers and when I couldn't find them in the common parts catalog I assumed there was no point in searching further.

None of them were listed!
What are the odds of that happening?

At least two of them are recent numbers so I would think they can't be
obsolete.
They are definitely Probe cables so I thought for sure they would be there.

Re: Tek 2782 Schematics Uploaded to KO4BB

josephlevy
 

Hi
I conversed with the (now the 'late') great Dean Kidd abt. 10 yrs ago and he said that Tek never got the 'service manual' for the 2782 to more than 'beta' thus could not be procured...

He said he had schematics and I foolishly did not ask for them then (the 2782 was working fine,(a fantastic SA even in today level of performance!)
Then the 2782 failed and Mr. Kidd was not with us anymore....
Than you so much Bob Koller and KO4BB for uploading the schematics.

Re: vintageTEK museum releases Replaceable Parts Registry (RPR)

Dave Brown
 

These documents were on microfiche because they were sent to the field offices and they required compact storage. Eventually microfiche was phased out by digital documents, probably by the mid 1990s. I don't know exactly when. We have some sections of a later RPR but it is not complete and doesn't cover any of the desired part numbers. 1986 is as late as we have at the museum currently.

These are scans from the 11"X17" set I have, sorry I don't have anything else.

Enjoy!
Thanks for the upload, Bob. I have been hoping someone would come up with these!

If you ever have to build a replacement mechanical part for a scope,
this information may be useful.

I'd say also that things about 3D printing may be useful to make some
brackets, perhaps knobs, and fasteners.

Somewhere in time, the supply of used mechanical (and electrical)
parts will run out. Some can be made, some can be substituted for,
some (mostly the CRTS) cannot be.

Tek's new president tours vintageTEK

 

I thought these two articles would be of interest to the group.



<https://vintagetek.org/tektronix-presidents-tour/>

<https://www.oregonlive.com/silicon-forest/2019/01/tektronix-names-new-presi

https://www.oregonlive.com/silicon-forest/2019/01/tektronix-names-new-presid
ent-marc-tremblay.html



I found the last paragraph of the 2nd article to be particularly interesting

"Once Oregon's signature tech company, Tektronix is now greatly diminished
but remains among the state's largest technology employers. It employs
hundreds, perhaps more than 1,000 (Fortive won't say how many) at its
250-acre campus near Beaverton."

I have a bad psu in my TDS-420A , it burned a track on the pcb bur I cannot find the cause , the switching transistor os it seems . I have had it suggested that the hybrid device is probably the fault , does anyone know what the device consists of , or better still does anyone actually have one that they would part with .

Thanks in advance for any help you can give

I just finished two of these PSU's, I think you need to replace ALL of the
small electrolytic caps, don't bother testing, etc, just replace, they are all
past it.
One of the problem areas in this unit is the black potted mains switching
circuit in the primary. It controls the input doubler configuration by
automatically sensing 120 vs 240 mains input. It can be removed and jumped
across.
The other issue is the regulator board mounted vertically near the output
connector. These can get dirty from the fan, causing leakage paths, and
subsequent erroneous shutdown signals.
That is identical to the power supply I just fixed. Every single capacitor on the power supply board was bad. Either in the process of leaking or already leaked out and dried out. After replacing those and the all know SMD caps issue all seems well. You may want to check that the output connector joints are solid as well,just in case.

Very nice information. Is anything like this available for after 1986, say 1986 through 1995? I'm looking for 2465B/67B information.

If only Tek released their source control drawings, wishful thinking.
