Could someone tell me if there is much difference between the 475 and the
475a.Reason is i bought a 475 and it and it has a few lights out and a few
broken knobs.I can get a broken 475a pretty cheap and was wondering if i
could use it for spare parts.Thanks for any help u may give me.

I have a TM-501 that looks like the Bridge Rectifier (CR-10) has
died. Probably wiped one of the caps too. Does anyone have any of
these ?

P/N 290-0577-00 2000 uF Cap (Need 2)

P/N 152-0488-0 Bridge Rectifier
(or what the pin connections are !!)

Tnx Dick, W1KSZ

Hey ! Don't lose your hope. WSTR0DEM just changed its extension
from .zip to .exe (AFAI see). To get it, you just have to log-in to
ftp://ftp.tek.com/mbd/support/ , and then download WSTRODEM.EXE. Or
just click (or cut and paste) this link (
ftp://ftp.tek.com/mbd/support/wstrodem.exe ) into your browser, and
there you go !!!
Tell me if I can help you on this.

ON a marginally more positive note, does anybody need a 564B CRT?
I am breaking up an old unit, tube and filament looks Ok, but no use
to me, if somebody will pay the postage to ship it. I also have
posted a bunch of cleaned older Tek knobs up to our site for those
refurbing older 500 series units. More going up later today that are
in the later "dark gray" style.

Suzie is going to Portland next week to pick up a case of Tek blue
paint in spray cans, we just couldn't figure out how else to ship it.
we will have a lot of it, if anybody wants to drive up here to BC to
get it!

all for now,

Thanks to everyone who answered my question on the 465 scope probes.I really
appreciate the help.

probes

Bill <mbhcomp@...>
 

Can someone tell me what probes are compatable with the 475?If the list is
to long can u tell me where to look.I go on ebay sometimes but i don't know
which ones to bid on.Any help would be greatly appreciated.

Re: P6106A vs P6053B

Craig Sawyers <c.sawyers@...>
 

Could someone please tell me the main spec differences between the
TekTronix P6106A and P6053B probes? I acquired a 6053B, but can't
find the specs anywhere. Want to use with a 475 scope. From what
little I have found, the 6106A appears to go a little higher in
frequency than the 6053B.
According to my '88 Tek catalogue, the "recommended" probe for the 475 is
the P6106A, but the P6053B is a "useable combination" with the 475.

Detailed specs depend on cable length, but picking a 6' for comparison we
see:

P6053B
======
10M, 12.5pF. 200MHz at -3dB, 500V DC max. 15-24pF 'scope loading.

P6106A
======
10M, 11.2pF. 250MHz at -3dB, 500V DC max. 15-35pF 'scope loading.

So all in all, very similar. In 1988, the P6053B cost $150 and the P6106A
cost $140.

So not a lot to choose between the two, really.

Re: P6106A vs P6053B

jd_hurst <jdhurst@...>
 

The 6106A is a somewhat newer design, and yes, it is good to 250Mhz
with a fast enough scope (with input of 1MOhm and 15-35pf), while the
6053 is good to 200Mhz with a fast enough scope (with input of 1MOhm
and 15-24pf). The input capacitance range is similar enough though,
that you 6053 should work just fine with your 475 under most
conditions. It just won't deliver proper response past 200Mhz.

Hi,
Could use a little help with this one, The problem is that the
display takes a long time to appear then slowly expands and contracts
with some stable periods in both positions, this coincides with the
HV test (R1274) voltage varying. the low voltage supplies are stable,
so I suspect the thickfilm net work (307-0359-00), but cannot find
one to try, has anyone tried discrete resistors to replace this?, or
have any ideas on the fault?. Has anyone got this part for sale?
Thanks,
John.

Hi Walter,
Like the other note here, I sympathize with you. Have you looked at
the site: http://www.elbol.com/hamtafiler.htm ?
The site is in German, and it looks to me like the software is demo
software, but they mention WSTR31 and WSTRO. Might be worth a try.

Oh boy. I can't help you with the software, Walter - but you have my
sympathies. I would bet that Tek's attitude would have been different if
you were dealing with them in the '60s (but you wouldn't have had a software
problem back then ;-) ).

Good luck in ferreting out the software.

Fantastically frustrated with Tek, really need help

 

After a complete day wasted getting the wrong info from Tek,
and eventually no help whatsoever, I could use some assistance from
the group.

I have a working and lovely Tek 2221A digital/analog 100Mhz scope I
just got, and want to use the serial port to download data, a
function they intended, and which is described in depth in the
manual. the original PC software the manual describes, something
mysterious called S41SAVE is now lost in history, and was replaced by
the all-singing-all-dancing Wavestar. After contacting Tek, I was
told to buy this program, assured it would work with my scope.
However, I read all the notes and pdf's on line, since there was no
demo to test, and found, in fact, NO, it would not work, and I re-
contacted my rep with this data, who then suddenly (and
authoritatively) advised, no of course it would not work, my scope is
out of support. Quite a course correction in just a few hours.

This is great, the current verison of wavestar DOES NOT support my
scope, only older versions do (which they will NOT sell me), with

Tek 453

Collin
 

Hello friends,
I have had some difficulty with the 453. The channel 1 position all of a
sudden went way off the display. I could not get it back on the display.
Tapping the mode switch seemed to affect the position greatly. After much
tapping and adjusting of the position control the trace was back where it
should be. I feel that a vibration of the mode switch will send the trace off
again. Any ideas? I looked at the mode switch very carefully and all looks
fine. This is a very clean 453. No dust and the switch looks very clean. The
contact for channel 1 looked like it was making good connection when
switched. Thank you.

Collin

Hi ppl i'm new to the group and was wondering if someone could give me an
idea on my tek 475 scope.I just bought it and channel 2 is great,but channel
1 when you first turn it on keeps going upward,turning the position control
will bring it down for a minute but it keeps on climbing.Eventually it goes
right off the screen.Any ideas would be greatly appreciated.

Re: Digest Number 446-New to me 535A Questions

Bryce Ringwood <bringwoo@...>
 

Hi all,

Looks like my 'D' type plug in is busted too :(

Or I need to RTFM. Will look at the connections suggested by David Wise
first. Then go through it logically until the fault is traced. (He said
confidently). The manual for the thing is rather interesting as it has a
price list and catalogue for all the Tek stuff made at the time appended
to it. Tubes were all $75 to $100.

Oh, and my scope is the 535 'A' version also. Looking at these manuals,
David is quite right. There are tons of minor modifications that relate
to specific serial numbers.

535A,547,549s,575/175 D,1A1,1A4,CA,M,Q(!) and TU2 Q untested, D Busted.
