Hi Don, Very interesting response. My comments are below:

Just poured the CRT of my just acquired 5111 all over the bench (thanks UPS). This was a 5111RM replacement for a 5111/spectrum analyzer that was very tired. Let me know if you have any of the

help! Need several rotary swiches for the Tek 2235 Oscope. Part# 263- 1040-03 and 263-1041-02. You may have another name for these switches like cam assy. They are basically ch1 and ch2 switch assy,

Chris Curtin was kind enough to answer some further questions I had, so I thought his answers might once again be of interest to the group. As before, my bit is prefaced with "Q" and Chris'

I am moving to a new home and I am packing away all my books. I found some of the books I bought while at Tek. They are: Sampling Oscilloscope Circuits: Tektronix, Inc. 1970 Spectrum Analyzer

That's a new number on me. This list you suggest would be particularily hard for me to make since I am aware of a lot of obscure instruments that never really made it into production. I wouldn't

Need the round CRT cover (if that's what you call it) that bolts on to the front of the 555. If anyone can spare one of these let me know. Just acquired one of these units and this is missing from

I received comments from Chris Curtin and thought they would be of interest to others. For lack of more imagination, I've identified my comments with "Q" and his with "A". Here they are: Q. One

Does anyone know where I can get a schematic for a Tektronix 515A. Please email me at brrunner@...

Hello everyone I have a Tek475 that is not dead, it is almost dead. It worked fine last night. This morning I turned it on and no trace but indicator lights work and the fan works. With no input and

we overhaul all the 400, 2000 and 7000 series pretty regularly, and note that it is usally NOISE that affects spot size in the 400 series. as the scopes age, there are many, many grounds (with

Can anyone use a Tektronix 4696 color ink-jet printer? This unit was used with many pieces of test equipment and computer terminals. I can't test the unit since the cartridge ran dry while it was

I finally called Chris Curtin up tonight. As background, Chris had design engineering roles for oscilloscope and computer terminal CRTs; and then was Manufacturing Manager of the Tektronix CRT

The orignal post (Thu Jun 27, 2002) said, in part: "The trace is fat, about 0.15 [divisions] wide regardless of whether the 20MHz BW limit is engaged or not. This fuzzy trace isn't the usual scan

This whole "fuzzy trace" issue has me somewhat confused. I thought I understood it since I lived through the era when it orginally came up. It was never an issue until the 465 was introduced and

Hi all, :) Anyone ever hear of a Tek 488? Anyone know of a definitive list of all Tek scope models ever made? Might be a nice little project for someone... cheers, :) Michael

Noting that some list members are busy restoring (or trying to restore) 500 series scopes, I though this might be useful. I recently bought a big box of salvage from some Tek 500 series scopes,

Each pair of tubes are boxed together (except as noted) and have matching test number / part number tags attached. All are plus shipping. 12BY7 Tek P/N 157-0053-00 Selected pair, 4 pairs
