Tektronix 564B storage oscilloscope / damaged component

[Andreas Horneff]

Hi!

I've got an old Tektronix 564B storage oscilloscope and now I've got a
problem. At the back of
the oscilloscope are four components (they are visible without opening the
machine). Now my
problem. The upper one on the left side is missing and I haven't a user
manual, so I don't know,
what kind of component it is.

Can anyone who has a Tektronix TYPE 564B storage oscilloscope or a
usermanual check up, what is written on this component (what kind of
component it is) an post it, or email it?

Thanks a lot!

Maybe electrolytic caps? Without a picture,it's anybody's guess.
You didn't even describe the other components around it.

(and a user manual is not going to be of any use,you need a service
manual.)

Hi.

If you are having a 564B storage oscilloscope, you know what component I'm
talking about. At the back of the machine, there are only four components,
installed on the cooling element.
It is looking like this:
____________________
| |
| X O |
| |
| |
| O O |
| ___________________ |

The 'X' stands for the element which is damaged.

Maybe it is an transistor, but I don't know, what kind of element it is.

Thanks,

Andreas

There are 4 TO-3 devices under plastic insulators, all mounted on a
large finned heat sink on the back of a 564B. Mine is sitting right
here, but I can't seem to lay my hands on the manual today. I'll
continue to look. I'm sure it's right here close....

Do you mean left side as viewed from the front or from the back?

Hey, that's very nice of u!!!

I mean left side viewed from the back.
You are talking from the right components, they are, like you have already
said, on the large heat sink!

THANKS!!!!!

There are 4 TO-3 transistors there. From the manual, I can't tell
which are which, but I THINK they are these 4 tek items. Since you've
got your 564B already in front of you, perhaps you can tell which you
need by process of elimination.

Q32, Si NPN, 151-0149-00 (2N3441)
Q51, Ge PNP, 151-0165-00 (2N3614)
Q74, Si NPN, 151-0256-00 (Tek Spec)
Q96, Si NPN, 151-0256-00 (Tek Spec)

This info comes from a manual that covers past serial #B240000,
Mod121N. I'm pretty sure the Mod121N isn't important to these
particular parts.

If your other 3 don't fall into this group, then let me know and I can
dig deeper.

If the one you are missing is one of the Tek Spec transistors, then I
suggest that you contact Deane Kidd to see if he has one. He would
probably also have the insulator/covers, etc for these, too. I can
send you his email address if you need it.

If you want to try to wing it, it looks like these won't be called on
to see more than 150V, probably less. They are just used for PS
regulation, so they don't need to be fast, but they might have to have
a rather high power rating.

Ok, so far so good.

These transistors are still ok:

Q74, Si NPN, 151-0256-00 (Tek Spec)
Q96, Si NPN, 151-0256-00 (Tek Spec)
Q51, Ge PNP, 151-0165-00 (2N3614)

=> I need this one:

Q32, Si NPN, 151-0149-00 (2N3441)

Now I've got another problem. I can't find a shop where I can buy this kind
of transitor. Can I also use a transistor with that specification:

2N3440 (Si N 250V 1,0A)
or
2N3442 (Si N 160V 1,0A)

What about the design, what dose Si NPN or Si N stands for? Descripes it the
design? Maybe you can help me to find a shop where I can buy this
transistor.

Thanks again,

Andreas

Si= silicon,Ge= germanium ;basic material of the device.(different Vbe
drops)

NPN and PNP are the structure of the transistor,like N-channel or P-channel
FETs

Since these appear to be in the same family, I would go up in voltage
and choose the 3440. I'm guessing the 3441 was in between.

I'm not familiar with that database, but it sounds very useful. Is it

That's my guess,too.
Probably most any GP transistor meeting or exceeding the 2N3441 specs would
work.

In the case of this part, I can't tell who the actual manufacturer
was. Maybe they BOTH bought it from someone ELSE. Or maybe one bought
it from the other. Or maybe, for one of those reasons or some other
possible reason, the two parts are just equivalent. I can't tell, from
the database, in this case. And I haven't tried looking anywhere else,
for information on that Delco part number.

I'm not familiar with that database, but it sounds very useful. Is it
available on-line anywhere?

Jim,

It's the "Federal Logistics" database, published by the Defense
Logistics Information Service (DLIS). Their website, at
http://www.fedlog.com , says that it has information on over 12
million part numbers and over 7 million stock numbers.

I think it's normally available only to government entities and
gov't-sponsored contractors. I bought my copy (the 2002 version), on
six CD ROM disks, from somebody on line, for something like $55. Many
U.S. companies have copies. And they usually have subscriptions for
automatic updates, which might mean that there are older copies
floating around.

It has been *extremely* useful, for me. Normally, when I search for a
Tek part number, I get all of the equivalent part numbers and all of
their suppliers' info (name/address/phone), plus, usually, technical
SPECS of the device, original acquisition price info, et al. (This has
even worked for some Tek parts that Tek doesn't list any other
supplier for.)

I can also search for an equipment model number, which usually gives
me all equivalent models (e.g. miltary vs commercial designations),
plus specs, etc, and, sometimes, the TM or TO numbers of the technical
manuals. Adding a wildcard to the end of the model designation gives
all of the variants, such as models with certain option packages, A
and B versions, etc.

Searches can be combinations of NSN (National Stock Number),
part/model number, item name or type/function, supplier, and
manufacturer's/supplier's code (CAGE). So, for example, I could find
all items with "oscilloscope" in the item name that have "Tektronix"
as a supplier (726 items). Or I could find all scopes that have a
model that starts with "2235", or "AN/USM-488" (which is the mil
designation for a 2235 model). "2235*", for example, shows records for
eight variants, with five distinct NSN's. Searching for all part
numbers that start with "151" with supplier "Tektronix" gives 548
records for Tek transistors. And searching for all items with
"semiconductor" in their name with a supplier containing "Hewlett"
gives 2318 records, mostly diodes in this case.

The database seems to have everything from horse bridles to high
technology, and many of their individual parts, as well.

Tom Gootee

Thanks, I think this has come up before, but you've given the best
