Weird transistor with six leads

[Ernie Werbel]

I was going through some stuff and came across a weird transistor. It is in
a TO-5 case but it has six long, gold-tinned lead wires coming out of it.
There are no numbers printed on the case. I was wondering if this is maybe
two transistors in one case perhaps? There is only one tab. I have never
seen anything like this before. I wonder how old it is.

possibly a matched pair of transistors, or some sort of integrated circuit.

Most likely. (They will be tightly matched)

Their matched temperatures (because they are so close to each other)
is another advantage

Others have guessed "IC".
Probably not: TO-99 has 8 legs and TO-100 has 10 legs.

This is how ASCII art looks to most Usenet users

when you try to do it in a proportional font:
http://groups.google.com/group/alt.electronics/msg/6e4195e795dc425d?dmode=source

Do your drawings in a monospaced font like Courier
then paste that into your post.
Notepad is one solution.

Thanks for the link. This is pretty intriguing for me. I love vintage
electronics. I have not seen anything like this in my 10 years involvement
in electronics so I would have to imagine it is a vintage item.

Thanks, Jeff, for the tip. I am using Outlook Express, and set it to "text
only" but the only font that appears now it Times New Roman. Do you think
if I (can figure a way to) set it to display Courier that would fix the
problem? I have tried posting in certain fonts using HTML and that got
people annoyed. I am suprised that so many people cannot view HTML in
newsgroups. I am running Windows 3.1 and can do it with no problem so I
figured everyone else would be able to. Guess I was wrong.

Hmm... a dual transistor could make sense. That would actually be quite

useful come to think of it and in that case I can't see why I don't see
these more often. This is the only time i have ever seen one in my life.

As for an IC, I guess anything is possible. An op-amp perhaps? Yes I do
think that could be feasable and utilize 6 pins:
1.) V+
2.) V-
3.) Inv. Input
4.) Non-Inv. Input
5.) Ouptut
6.) Shell as ground? Or maybe since it is a microcircuit, it can connect to
the grounding plane of the circuit?

Am I missing any pins here?

I suppose anything is possible. There are plenty of voltage regulators that
look like ordinaty TO-92 and TO-220 transistors. Perhaps it is a dual unit
even? Like having a 7805 and 7905 in one case or something like that?

This is quite a mystery to me!

Hehe well it doesn't look to have any leads broken off... (-:

I'm not interested enough in Outbreak Express to do much legwork.

No surprize to me.

I am suprised that so many people cannot view HTML in newsgroups.

It's not a matter of *can*. You don't know your history:

Usenet

existed **BEFORE** HTML and www --even before the Internet..
http://66.102.9.104/search?q=cache:_kq6h6G9wzQJ:en.wikipedia.org/wiki/Internet+zzz+1-January-1983

Usenet (outside the binaries groups) is a plain-text medium
--no formatting; no attachments.

That you are using a tool poorly suited to the task is another issue.
Micro"I've got a better idea"soft perverts every idea it touches
--including Usenet.

Microsoft is excellent. Not sure what you use, but I wouldn't use any
third-party software. Who knows what you're getting along with it. As for the
plain text issue they can get with the times, and turn HTML on. It would make
it a lot eacier, and it would still display plain text.

Outbreak Express is second in crappiness only to Internet Exploder.

More drivel (even if I could parse what you wrote).

Now you're just being pig-headed and ignorant.

Maybe it has something to do with reading comprehension

I agree with you on that one, which is why I have stopped upgrading. I am using
Windows 3.1 and have maxxed out my system to my satisfaction.

You come off as being small-minded and ignorant. Why don't you back your

argument and say what you don't like about it?

I don't like it either but things change. Maybe you just can't keep up with the

times. Do you still drive to work in a horse and buggy? Come on, HTML has been
around for more than a decade.

That's what a lot of ignorant people say

when they see someone who is informed and opinionated.

Why don't you back your argument and say what you don't like about it?

The reasons are legion. Start with the fact that OE is a mail client

with a last-minute, hung-on-the-side Usenet hack.
(M$ doesn't think enough of OE to include it in Vista.)

The times are just fine. The problem is pig-headed fools

who can't accept things that are just fine the way they are.

If I did, I wouldn't try to take it out on the superslab.

Rockets exist--but I would get into a Model T that had one strapped to

The word you are seeking is "appropriate".

Come on, HTML has been around for more than a decade.

Usnet users have been getting by for decades

without a markup language.
If you don't like Usenet and it's minimum-bandwith nature,
there are lots of Web-based forums.
THAT is where HTML is appropriate.

Well that's a shame to hear, although I won't be getting Vista. 3.1 works well
enough for me.

Ok I'll give you that. But I have to say it works fine for what I do. Email
and newsgroups. I do like the interface though.

Not I. I am perfectly happy staying in 1994. That time was just as good as any
