I'll try to keep this brief, but this is an end to end diagnosis and repair description. Maybe this will help someone in the future who has a 465B or similar scope with a similar problem? Experienced

The info on TekWiki is obviously wrong. 154-0838-00 was used only 2213 and 2215. 154-0861-00 was used in 2213A, 2215A, 2235 and 2236. Check out this old post on the same subject:

Hi Dave, Can't answer your question on the substitution, but I believe that I have a good used CRT for the scope that you have. Let me know off the list if you would like it and we'll make a deal.

It is a well known issue in the 224x series scopes power supply that any original rectifier diodes marked ZM or ZS tend to get leaky or fail over time. There is a total of 17 diodes that should be

Hi all, and thank you Mark and Gerald for the files and the hints. I found out, that the EMI Filter is blown. But I think it's not so easy to repair, because it's filled with epoxy. Perhaps I will

The input is a sine wave. The wave form cause is a single component.

That didn’t take you very long. You get an A+.

Hi chaps. I suppose this is the final update, as found a shorted 47?F 20v cap (C6033) on the A62 board, and now the 492 appears to be working again (although I don't yet know how to use it, to

Hi Benny, I'm interested in replacing the rear feet on my 'ol Tektronics 475. Do you still print them? Price on 4? Thanks Stan W8SRD

Hello All, Back Story: Bought a cheap 2213A off Marketplace with fuzzy display issue, Fixed issue by replacing focus resistors, discovered screen damage in that there was trace distortion in lower

Are the voltage’s adjusted with the VR’s on the plug-in Or is it an adjustment inside the scope itself?

What are??? Nothing quoted for context. Glenn -- ----------------------------------------------------------------------- Glenn Little ARRL Technical Specialist QCWA LM

Hello, I posted a picture in photo of a waveform being drawn by an DC502. I asked if anyone wanted to guess the cause. I know the answer, but take a guess if you want. I will post the component

Chris, I could use the case if it’s available. I’m in Wichita Ks 67212 Craig

Where are you located? I think I have a complete (maybe working?) 468 in the pile of extras.

Is it adjusted using some of the VR‘s on the plug-in

Yes they are

Great reply from Jared, covers pretty much everything. I would add, unlocking 1GHz means you probably need to re-do parts of the calibration. Also I question the actual usefulness of that extra

According to both the manual and catalog from that time the TDS684A doesn't have any options that can be unlocked. Also the full 1GHz bandwidth applies only to attenuator settings 10 mV/div and

The TDS684A is definitely a 1GHz scope, running at 5G Samples/sec. Here's info on replacing the CRT with an
