Re: Tektronix Spelling

Yes it is worth doing because I tried just one mispelling and found a
scope.

475 focus pot needed
Hi all!
I am in need of a new "focus" pot for my Tektronix 475 scope, serial number B278849. The part Identifier is R1380. The Tek part number is 311-0075-00. Description is: Res., VAR, NONWIR: 5M Ohm 20% It is a small all metal round pot with a 1/4" bushing an an 1/8" shaft. The pot works electrically but is binding/stuck mechanically. It can be rotated, but it is very, very stiff. I'm afraid of breaking the fiberglass extension rod. Tek, of course doesn't have it, and though it is a simple pot with no special push-pull switching, etc. 5 MegOhm is not that common a value any more so I have not yet found a quality generic replacement. I assume that this pot has linear taper. Thanks for helping. Steve Hogan Can someone out there he |

CRT Wanted
Darrin Conniff
Greetings All,
I would like to inquire if anyone in this fine group of ours has a CRT for a Tek 2235, or 2236 for sell, or trade. The part number on the CRT is 154-0861-00. I received this 2235 from another TekScopes member after I begged on this group for any source of Test equipment in Texas some weeks back. I was delivered a fine selection of Tektronix equipment, at an excellent price, but this tube seems somewhat elusive. If anyone has an extra, or a 2235 or 2236 they have stripped for parts, except for the CRT, could you please contact me? The 'Scope is in pristine condition, except for the CRT, which is obviously at atmospheric pressure. Best Regards, Darrin |

Re: Tektronix Spelling
Rex W. Athey
In the movie, "Diamonds Are Forever" they have a company called "Tectronics". I believe I have it spelled the way they have it in the movie. I'm to lazy to pull out all my James Bond movies (and I have ALL of them!). They have a nice 500 series Tektronix scope in Dr No. They have the infamous Telequipment S51B in both Goldfinger and You Only Live Twice. And they have either a 453 or 454 on the boat that is NOT a chase boat in "You Only Live Twice".
They also have S51B in most of the Gerry Anderson series like "Thunderbirds", There's a nice close up of a 54? (I think it's a 547 or 545) in the opening sequence of Journey to the Far Side Of The Sun. The Real McCoy has a nice 200 series (221?) and I forgot the name of the movie from the early 80's with a girl electronics engineer and her airplane flying boyfriend. In the car outside the lab they had a spectrum analyzer and a Tek scope in their car (Prime Risk seems to come to mind as the title, though it was a "B" picture. And Dark Angel has an RM503 that gets smashed to pieces at the end of the second season (so sad! I use to have 3 RM503's and 2 503's). I wouldn't be surprised if Tek was in Irwin Allen's stuff or the original "Mission Impossible" with Barney Collier. I always drooled at all the gadgets he would pull out each week. There are many more oscilloscopes in TV and Movie land. The Oscilloscope always makes it own statement in a show. Rex W.

help with 2465
has anyone seen this when the scope is first turned on
and a signal applied there is what looks like ac ripple on the top of the trace but after a minute or so it gradualy shrinks and goes away alltogether is this a sign of of serious problem everything else workes fine thanks ken magers __________________________________ Do you Yahoo!?

eBay scope
Craig Sawyers
Interesting and good price rare item lurking on eBay at the moment. A 7514
storage scope - I had no idea that Tek did split screen storage into the 7000 series until I saw this. 90MHz bandwidth. Anyway with an interesting set of plug ins, he has it on for $75 buy-it-now. Item number is 3802548425 Craig |

nailed down, so that it is lower half of PROM that is read. As for 2764, that is a different proposition because it is 28 pin DIP (four pins more than 2716 or 2732), but doing a jerry rig to translate pins would make it usable. You have also to watch programing voltage. Some of early PROMs used 21V, then came 15 V, then 12 V. You can program 12V device on 15V programmer setting, but there is no promise that device will not be damaged. Another consideration is speed, but as densities went up, so did the speed. If PCB is poorly decoupled, higher speed might work against you, but that is not very likely to happen. Regards Miroslav Pokorni ----- Original Message -----
From: "Bruce Lane" <kyrrin@...> To: <tekscopes@...> Sent: Sunday, March 07, 2004 2:31 PM Subject: [TekScopes] Another new file With thanks to 'Greyhawk,' a pair of firmware image files for the 7B90P programmable timebase are now available. Note that these images are 2048 byte, meaning that they were most likely designed to program into a 2716. Considering that 2716's may be pretty hard to find, advice on whether they'll work in a 2732 or even a 2764 would be welcome.
