. . . . though I haven't bought from them, Hudson has a pretty extensive

Deep-drawn aluminum cans can be ordered from Zero Mfg.

https://catalog.zerocases.com/category/deep-drawn-cans

They are not cheap, and you'd have to work on any kind of crimp seal
for the part size you're interested in.

Re: Multi-section electrolytic capacitors from Hayseed

Ed Breya
 

I think people have been searching for new empty capacitor cans and base parts for a long time. I've never seen any reports of finding these things, although you know somebody must make them still, to supply cap manufacturers (unless they make their own in-house). Metalworking outfits that do Al drawing and tubing would likely be the suppliers, but only in OEM high volume contract situations - I doubt that you'll find retail small quantities.

Most people just rebuild from the old parts, using various well known techniques. I myself am of the un-crimp - re-crimp school of thought, and have had great success many times. A carefully done crimp method can work nicely about twice - once the first time, leaving the cap looking nearly original, and a second time if necessary again, but with uglier results as the crimp edge material degrades. Beyond that, it still works, but likely needs adhesives, and gets uglier yet.

I save any twist-locks and shot computer grade ones I happen to find, and keep them as-is, or gut them when convenient, and save all the husks and base parts for possible use. These are for maintenance only - I would never use a twist-lock for a new application, but I would use certain big old computer grade types, since I have a lot of still good ones.

Yes, of course they are separarate capacitors in one can. That is obvious.

The point of replacing a multi-cap can is to be able to keep the same form-factor.

Re: 465M Wave Forms

DaveH52
 

I'm not that familiar with the 460A, sorry. But yes the AuxTrigger/ExtClock on the rear panel. Select External Trigger from the Trigger menu. The gate out from the 465 is a 5V logic level so an attenuator is not necessary. Making this connection will provide a start of sweep trigger to the 460A so that troubleshooting the horizontal sweep of the 465 will be timed consistently. For most uses, just setting the trigger input to the channel of the probe you're using will work fine. Dave AC2GL

Well, the caps I opened were different, that's all I can say. I suppose if all the voltages are the same it could be a segmented capacitor but if the voltages are different they could not be.

Re: Multi-section electrolytic capacitors from Hayseed

Someone on news:sci.electronics.repair asked them about cans and bases.
They refused to make anything available except entire capacitors. I have
searched for a source of empty, new deep drawn aluminum cans with nothing
promising. It would likely take someone working in China to find a supplier
who would tool up and sell less than MOQ of 10K-100K units.
Emachineshop could likely supply the steel parts. I have access to a
limited supply of aluminum tubing drops from a local company that is 1-5/8"
in varying lengths. Grainger and others sell hole plugs that would close
the open end, yet allow you to reuse the container for future repairs. They
offer CAD software on the website to design custom metal parts. That would
just leave the need for new terminal boards for the bottom of the cans.

Re: 465M Wave Forms

Harrison
 

Thank you for the clarification Dave. The markings on the different BNCs on the back of the 465M is very clear and descriptive (matching the labeling used in the Wave Form section of the manual). I must ask just to be completely clear; When you refer to the "A EXT Trigger" of the 460A, in your answer, are you referring to the single BNC on the back of the 460A labeled "Aux Trigger/Ext Clock +6V. I ask because scope use is not a norm for me and I don't want to damage either scope by a wrong hook up. Also, do or should I have an attenuator or such in the cable hook up to protect either scope?
Finally, what is the intent of the 50 Ohm cable between the 465M and the 460A (Between the scope under test and the test scope.)? If you have the probe on channel 1 of the test scope and are probing the scope under test, what is the 50 Ohm cable doing for you? I don't question the instruction I just am trying to understand why the set up is this way. Harrison N1FAM

Hi everyone. I hope you are all doing well. I recently purchased a Tektronix 1107 dc supply for 2200, 2400 and 2300 scopes. It’s kind of neat, mounts directly on the back of the scope. I tested it today and it looks like it is working. However I would like to have some sort of manual. If anyone has one or knows where I can get one please I would appreciate knowing. Thanks and stay safe please.
