Re: Looking for data on 9-pin Vacuum time delay relays used in old Tek-scopes
I still prefer the old original stuff as long as I can obtain it as I feel great respect for those people who have designed and made it. And it's fun watching it in operation! Anyway, the thought of

Thanks for your research, Jeff. I archived those auction pages since eBay will eventually delete them. Dave Wise Sent: Wednesday, July 21, 2021 4:43 PM To: [email protected] Subject: Re: [TekScopes]

Re: in-circuit capacitor testing (ESR tester) -- ideas appreciated.
Forget IET, which was unhappy that the original 5000 was competing with their higher prices reselling it. So they invented the 6000, which has one spec slightly improved. In Germany, it is easy to get

Re: Replace/Repair TM 500 Module Side Panel Latch
I hear you, although I seem to remember you can use other authentication providers to log in to ShapeWays. Maybe that'll work for you. I don't think they charge anything extra for one-offs, as their

Hmmm¡­I looked up the -5000 and apparently it was replaced by the -6000. I looked that up and it has been replaced by the -1920. $5000. DaveD

I was trying to avoid creating yet another account with yet another password on yet another website merely for the purpose of determining a cost for something but I suppose it's necessary. This would

Re: in-circuit capacitor testing (ESR tester) -- ideas appreciated.
I would note that the IET DE-5000 is a rebadged DER EE DE-5000 (I own the DER EE meter). I bought a second alligator clips module (TL-21) and converted it to Kelvin clips. It does pretty much

Re: Replace/Repair TM 500 Module Side Panel Latch
These are tiny parts and I feel the price for each is quite ... exorbitant ... especially once you add shipping to the frozen tundra where I live - Canada. The/a/one problem is that there's a fixed

Re: in-circuit capacitor testing (ESR tester) -- ideas appreciated.
I use one of these also, very good little device, I have no complaints. Useful as a regular old milliohmmeter with the Kelvin clips also (I added these as well).--EricSent from my Galaxy

This one works well in circuit and is easy to build. Bama Manual Archive (edebris.com) <http://bama.edebris.com/manuals/creative/esr> It doesn't have the greatest resolution for very low ESR caps, but

Recommend. Another good, but even cheaper addition: Mastech MS8911. (Don¡¯t fall for the MS8910, which is not very useful.) The MS8911 has a 0.1 V mode which can be used to avoid switching on

Hello Siggi, I notice the price for your parts is quite inexpensive. Is that price set by Shapeways? I ask because I have a small 3D printing job that I would like to have printed and wondering how

Re: in-circuit capacitor testing (ESR tester) -- ideas appreciated.
I use an IET DE-5000 LCR meter. Mine has both tweezers and Kelvin clips (i installed these to replace the alligator clips that came with it). It will test ESR at 100kHz and capcitance at 100/120/1k Hz

Shapeways shipping to UK has got stupid expensive lately. I need to find a UK based 3D printer that will SLA print in nylon. PS If I do find someone, will you make the models available for DL? Thanks

I modeled these up and put them on Shapeways, and I understand some people have had success with those. You can buy prints, or you can download the models and print them yourself. Here are the links,

There are existing 3D models for these. I'm not sure where I got mine, probably Thingiverse or Tinkercad, but I've printed a bucn of them and they work. I'm happy to supply either the models via email
