New to group - Just acquired a R7844
Hi All:
I just found a working R7844 with 7A26, 7A24, and two 7B85 plugins. I was in a pawn shop and saw it on a shelf in the back room. I asked the owner and he said it had been sitting there for 5 years and he did not know what it was. He brought it down and I powered it up. Nice bright traces and ran a wire to calibrator output and all channels worked.
The best news is he wanted it off his shelf and asked me for an offer. Just for laughs I offered him $40.00 and he couldn't say yes quick enough. (guess I should have offered $20.00).
I have used scopes my whole life but not one like this. Am still trying to learn how to use it as I have no users manual. Was able to use it this weekend to troubleshoot my Ham radio PLL with a 60 Mhz output that my old scope could hardly see. What a great piece of test gear!

Re: San Diego 7934 and goodies
Does a vertical amp anything useful together with a 7D20 in a 4-bay mainframe?
Not that the 7D20 in a 7934 makes all that much sense to start with.....
Looks like a bit of a mix, but should be a good deal if you can use
only some of the items.
I really wonder if the curve tracer those fixtures go with is anywhere nearby.
The current probe(s) would also be interesting.

I've got a Tek2205 which has been dropped and abused by the previous owner (I believe it's from a lab and the workers there did it to the scope when the lab was closing down). However the inside of the scope is almost new and very clean, everything works fine except the traces become distorted.
see video:
After I opened it up I have found this:
What a shame!
My question is that what Tek (or other brand) CRT can be used to replace the broken one? If repairing it is not economically viable I will offer it to people need parts to repair their Tek2205.
Thanks in advance

Hello, Gerhard--
Thank you for your
inquiry regarding the Tektronix C1001 camera.
Shipment via USPS
international Priority mail, in a
medium-size flat-rate carton will cost
$47.95, to which I would
add $3.00 to cover the PayPal fee and minor
shipping expenses.
I haven't had an opportunity to photograph the
camera and may attempt
to use a flat-bed optical scanner if it produces a
decent image.
Let me know if you're no longer interested, and thank
you.

Hello All: ? I am trying to repair CH1 on an AFG2020 I acquired some time ago. I have isolated the problem to a ComLinear CLC561AI amplifier located on the A42 output board. I cannot seem to find this part anywhere online.? I wonder if someone may have one of these they would be willing to part with. If not, I would also consider taking a complete A42 Board with the hope this IC works. ? Any help on a source would be much appreciated! ? Thanks ? Rich, AJ3G

I have attached the horizontal amplifier schematics (both for high &
low serial numbered units) & the A/B trigger generator schematic.
These are the missing pages from the manual that is available for
download.

Gang,
I’ve taken Tom’s dimensions and converted them to a scale
PDF. ?I then printed the 1:1 drawing on a laser printer, cut it out, and
dropped it on top of a 177 test fixture to test the accuracy of the drawing.

Before I junk part these out, perhaps there are some Tek collectors that need them.
For Sale: Tektronix RM561A Rack Mount scope. Dirty but seems to be fully functional.
Collection of various plug-in modules for this scope.
4ea 2A63 Differential Amp
1e 3A72 Dual Trace Amp
3ea 2B67 Timebase ( one black Face)
1ea 3B3 Delayed TimeBase
1ea 3A7 Differential Comparator
1ea 3A6 Dual Trace Amp
1ea 3A1 Dual Trace amp
All Dirty but all there and they appear to have basic function. Not fully tested.
If there is interest, I will fire up and test further.
See pictures here:
Would like to make a package deal for pickup in 48150, SE Michigan.
Or let me know what you need.
Maybe $50 for the scope and 25 ea for the plug-ins?
Thanks
Curt

Hello--
I'm offering free for postage (plus a sop to cover PayPal
and
shipping supplies) a Tektronix C1001 video
camera in unknown
operating condition; it appears to be in
good physical condition. There's
no mounting bezel for
the oscilloscope ,but a cable is
included.
Apparently, this device mounts in front of a CRT's
screen
and includes a CCD camera; see comments below from other
TekScope
readers for details.
If you need this C1001, please let me know and
I'll figure
out U.S. Postal Service shipping to your
location.
Thanks, and 73--

The C1001
only works if:
1. You have suitable camera adaptors for the scopes you
want to use it with
2. You have a power supply for it. You can either use a
regulated wall
wart, or wait until a matching DX02 supply turns
up
The C1001 is a fairly low resolution monochrome camera based on an
early
Sony CCD and boards, but perfectly suitable for the job as a scope
camera.
It has focus and aperture controls on the lens, and
magnification set by
moving the whole shebang along the mounting rails. It
produces NTSC
format composite video. It runs continuously, which is a
pain since
you cannot sync it to single shot events....
