RANTS!

This is to officially announce the posting of my RANT page. If you care, here's where to find it:




As the heading says:

Okay, I'm giving in to self-indulgent rambling. Here's my long-awaited list of Rants, Screw-Ups, Scams, Stupidity, and sundry Bad Things, for your amusement and my mental health. Sorry about the pictures. Only about 250K total...

Need Tunnel Diode for 547

 

Hi,

I am trying to bring my 547 back to life. It looks like the B
trigger circuit has a bad tunnel diode. Where can I get ahold of
this beastie ?

Thanks,

Terry, AB4UM


"Bookmarks" at the Yahoo site

Michael Dunn
 

One of the features of the TekScopes site at YahooGroups is a "Bookmarks" section, where we can enter web links of interest. Walter has already put his site address there. Anyone else with a Tek-related site -- feel free to put yours there too!

[Fwd: [JN] Nu Vistas : 7587]

 

This is from a post on Joelist (a vacuum tube audio mailing list). I
don't know the mailer or the tube dealer. If 7587 Nuvistors are useful
in any Tek stuff (it seems like I remeber this number), this might be a
usable source.

New group features

Michael Dunn
 

As some of you already know, eGroups has now been folded into the Yahoo groups family. If you're solely an e-mail user, don't worry, you don't have to change anything.

If you use the web site, you'll probably need to do some housekeeping next time you connect. It's not TOO painful.

The good news is, there are some new and useful web features:

1. When looking at the message list, you can expand it to show the full text of messages, not just the headings. Almost as good as an archive, which unfortunately is still absent. You can select how many messages are displayed in your preferences.

2. Even better, there's now a search function (I guess eGroups had something too, but it didn't seem to work very well if I recall). Type in a search term (e.g., Vineland, MkIV, SQ, 549 :-), and up pops a message list with all messages containing the term...

Re: Big Tek parts Index is on line now

If you haven't seen it, we have a large cross reference (about 2000
entries) of Tek transistors on our web site at
<> Click on the Tek reference area and look
around. You will find lots of interesting stuff there.

Big Tek parts Index is on line now

walter shawlee
 

We finally organized and posted all our Tek semiconductors,
along with cross ref data, and they are now on line
here:



we will keep adding more parts categories, like controls, knobs, etc.
as time permits. hope this is helpful to everybody. we will keep
adding more cross-ref data for those who just need to know what is
what, and can get the parts locally.

all the best,

8608

Michael Dunn
 

Yoohoo. I got a pair of NOS, Tek-boxed 8608 tubes for the vertical of my 556! They work great. Has anyone else had an 8608 fail on them. My bad one had a grid short. I noticed it because the vertical position knob acted like a light dimmer, making the tube glow incandescent white depending on the setting!!!

CRT Required For Sony/Tek 336 scope

 

I'm trying to locate a CRT to repair my Sony/Tek scope. The Part No.
is 154-0866-00. I'm willing to pay a reasonable price for one.

I would also consider purchasing a dead or near dead 336 scope to
salvage the CRT for my unit.

Regards
Rob.

Hi Rick,

I might have some of the caps you need but I will need Tek Part Numbers to
do a good search of my stock.

Camera Frame Adapters!

Don Crano
 

Anyone have or know where I might be able to get one or both frame adapters
to adapt to my C30 camera:

A 016-0269-02 for a TEK 475A to C30 and/or a 016-0248-00 for 7000 series to
C30.

Thanks in advance!!

Sick 7704A

 

Hi,

I just bought a 7704A which works, but poorly. It only has a
bandwidth of 170MHz and the tube blooms badly at a low intensity. It
looks like it needs a new tube but does anyone know whether a weak
tube affects the bandwidth, or do I have other problems?

My other 7704A was tested at the same time and had a 240MHz bandwidth.

Is there a source for replacement tubes?

Can someone give me a few hints.

Just a small thing. I have a number of TM500 modules with broken
plastic edges which look ugly. I have started to fix them by cutting
a section from the hood of a DB25 connector with a matching color.
Glue it in place with cyanoacrylate plastic cement and the device
looks good again.
