I was not part of circuit.)Not quite like that, there are lots of incidents where more than 1 phase can be found in proximity to each other, BUT it should never happen in domestic installations where it is possible that a non-skilled / qualified person could interact with the system behind the fascia. If you really need to use more than a single phase in a domestic installation because load balancing etc, then the phases should never be mixed within the same room. In a commercial or industrial installation, where it is not expected that unqualified persons should be accessing the electrics, then it is permissible provided there is clear signage of the danger.

The HP 54615B from CDL arrived yesterday with no damage and no obvious signs of futzing, complete with horizontal rolling fault on the picture bulb. CAL switch wasn't in unprotected position on arrival, it's hard to tell from the listing picture or maybe they read here.Some pictures of the insides which were cleaner than expected, mainboard with ST NVRAM module & Computer Products PSU module, I can only see one RIFA stinkbomb to replace. CRT monitor module is a Hitachi, but the picture bulb is Toshiba. I've replaced most of the larger capacitors on the CRT board, but as Shango006 often states it hasn't magically cured the fault yet. The horizontal hold control does work but it's impossible to get a stable display, currently looking at parts around the uPC1379C IC. David

Usually a Perilex. Every house and a lot of flats have three-phase. I had a 3-phase feeder to a connection box in my bathroom in one flat i lived in, so I could run a washer and a dryer.
Texio CS-4125A for 105$ is it good?
So...fast forward to today. There's only a select few cars in the American market that offer a manual transmission. The Civic still does. And if I happen to have someone in the passenger seat who never learned they are fascinated watching me row the gears but also remark that they want nothing to do with it. Can't drink coffee and eat a donut if you have to change gears. And....no one EVER asks to borrow your car.

Locally (Australia) that sort of scope runs from $50-100 USD plus postage. In the USA less.You should also be aware you are asking in the home of the TEA enablers if you should buy test equipment. The Answer is ALWAYS YES

The Answer is ALWAYS YES well, I am in Jordan and we don't have oscilloscopes here besides universities and so on. VERY RARELY someone posts it on opensooq (craigslist similar) and this time it is kinda reasonable price of 75 JDs (105$) and I can pick it up when I return home this Thursday.If I want to get the Rigol DS1054Z new it would cost me near 650$ which includes shipping and customs. No way I can afford that now. I need a scope to finalize my product (power supply for dreamcast) and start selling it in order to upgrade my lab ...etc. getting USB scopes like Hantek seems good but not for me since I want a real bench scope, and they will cost me more since shipping and customs gonna be not so cheap.I tried searching for analog scopes in ebay but no way near this price if you include shipping. shipping alone takes 130$ or so for a 30$ scope!The sellers says this scope is perfect condition with 2 BNC probes and fully functional. Original price was about 141$ but I got it down to 105$.I know you guys are enablers (nothing wrong with that actually) and you need a spark, but still I hoped that someone tried such a scope or brand to insight me more.

They moved the 3D Printing topics to a corner "Off Topic Hobbies" Off Topic 3D Printing? Electronics is the core of those machines....https://www.eevblog.com/forum/supporters-lounge/off-topic-hobbies/new/#new I do not understand.
The Texio CS-4125A uses custom Hybrid IC's as far as I know, so if it fails, it may be a difficult scope to repair. I would recommend trying to get a secondhand HAMEG as they were mostly made from off the shelf parts and can be found for relatively low prices.McBryce.
Hi,That is a good quality, medium complexity 20MHz 'scope of fairly late design for a CRT type. It will be fine for power supply work, also audio and lowerspeed micrcontroller work. I would take it over a Hantek "20MHz" USB any day. It was sold under the Kenwood name in NA ad UK. $105 is a fair price, they were $700 new not that long ago.Where in Jordan are you? I spent some time there in '96 & '97

Check opensooq jordan and see for yourself. If I was in USA, I would have searched through ebay to get the Hameg and other brands for sure.QuoteHi,That is a good quality, medium complexity 20MHz 'scope of fairly late design for a CRT type.

I spent some time there in '96 & '97I told the seller that I will take it. Actually, even if it is a bad scope... still the ONLY option available for now. Good to hear that it was a good one. Condition is perfect too.I live in Irbid and work in Ghor Al-Safi in south, near Karak. You used to work here? good to hear someone knows we exist

That’s looking hopeful. Do you have schematics for the monitor assembly? If not I think I’ve got them somewhere.
