Bonjour cher Monsieur bienvenu a liste Tekscopes. When working on CRTs, BEWARE of implosion hazard, wear gloves, face shield, eye protection as they my implode at any time. These CRT are available

This is called out in the service manual as part of the boot process Step 1 power on Step 2 buzz the relays Eric

Hey y'all! I am still working on this CG5011 with an interesting fault symptom - in 'Volt' mode, it basically AC couples the DC+/DC- frequency mode signals up to ~10V. Then at 10V, it starts

Eggie, Nice! That set is much better than what I have. I just have some generic small size bit kit I got from Amazon - very cheap. But it does come in handy. I need to get something a bit more

See this: http://www.condoraudio.com/wp-content/uploads/Projects/Tektronix-2465B-Oscilloscope-Restoration-Repair.pdf and also in my book Tektronix volume 2 you can find several notes on 2465 and

Pretty much any CRT from the 22xx series of scopes will suit your needs. I can get a parts 2215 for a low cost (I think), but I'm not sure. I'm not in France though so that is a problem. I wish you

Hi Frank, I bought then a Wiha PicoFfinisch 267P Set (T4-T9). Excellent Set. By the way Torx Drivers also fit Allen/Hex Setscrews in a superior way. Very handy when you must use force in releasing

I inherited a Tek 453. It was very dirty. When I press the beam find button I can get a momentary dim spot near the center of the CRT, but only a flash. What should I look at?

There's another degree of freedom to worry about, which is the relative position of the clump of windings along the body of the part - in one direction or the other, depending on which end can be

The calibration procedures in the 7704A manuals for Z-AXIS AND DISPLAY, section 8, "Adjust Auto-Focus Operation", describes how to adjust the gimmick capacitor which is a coiled wire around

Hi all, It's been a long time since I have been on the list, but I've been going through some things and getting ready to go through some more (this time another knee replacement). I have a Tek 310

Hi Ted, How are you? Is this still available? I am located in California but I would love to have this. I am also originally from Pennsylvania. I grew up in Chester Springs. Is it possible to get

I have a 465B for sale in Philly, only doing a local sale as it does not work properly. It powers on but the trace is distorted and only on the left side of the display. Happy to answer any questions

Are you familiar with the (typical) tantalum capacitor problem in tek equipment of that age?? The manufacturer said that the parts were good working too close to their voltage limit.? i.e. a 6.3

Thanks Raymond and Renee. I found the EEVBLOG 2465 Teardown but it just has pictures like I have been taking. I cannot find a reference to a specific capacitor that has failed. With the difficulty of

These power supplies use comb-like structures, connecting PCB's. The comb's square pins reach into hollow square "tubes". Good contact between pins and tubes is dependent on a tiny spring inside each

Sorry I know this thread is super old, but I'm looking at these relays (148-0128-03) on a CG5011 I am trying to repair. I used a T4 bit to remove the screws. so it seems Torx T4 would be the correct

sounds like possible cracked/poor solder connections or occasionally a bond wire issue occurs in a device... had a scan generator that took 6 months of chasing my tail to find a similar issue. turn it

It is nearly impossible to troubleshoot this power supply. I can see why people shotgun replace all caps. I cannot find any reference in this forum on a fault being traced to a specific capacitor. I
