    Don't kid yourself, China makes fantastic products. These junk consumer items pay the bills. They build these on spec for USA brands that want to sell junk. We spent 3 decades helping them develop sophisticated manufacturing and electronics. They no longer need US companies to innovate. Look at their space program or military innovation...

    Yes Marantz is still putting out components.

    Look on E-bay those old Marantz's are worth more now than when they were new some are worth up to a grand now.

    I get the Crutchfield catalog you can even get those McIntosh receivers remember the ones that cost a grand in the 70's? well now that is about 3-5 grand.

    I'm certain any plans that manufactures stuff can make great products or junk, its all in what they can get away with and still get the end consumer to buy. Sometimes you get what younpay for.

    But so many Americans are just cheap. We will buy our milk at the big box store the next town over cause it saves .12 cents and then bitch about the local store going under and not being there when we needed something super fast in a pinch. Our demand for stuff ever slightly cheaper has pushed manufacturers to find ways to make it cheaper......but also so they keep their profits up..

    We need to do our homework, and buy the better made versions on the market and yes it can be hard to tell which is the better made version. If we stop buying the junky stuff, hopefully make better stuff.

    So much today is built around planned obsolescence though its really tuff. I've had 2 new fridges in my house over the last 10 years, both had issues with fans, compressors, and leaks, and even when set to the coldest setting not be able to actually get to the temp set. I have a drink fridge in the garage, must be 25y/o. I can freeze my extra gals of milk if not careful and not even be to full cold temp setting.....that 25 dollar yard sale unit has saved me hundred in spoiled food on more than handful of times. I tried to do my full homework b4 spending thousands of dollars, read every review I could find. Funny thing is till these new models are out a few years there is no real world user reviews.....they are just opinions wowed by the newness.......
    Manufactures now change models so fast you no longer can get the user review how has had it for 2 years......that model is long gone.

    Its a tough spot between making budgets meets, balancing the wants and needs of household with only a set amount of money coming in. We all need our dollar to go farther, so we try to save a nickle where we can cause they do add up in the end......but we have to balance out the true cost of that saved nickle....and in today world of increasing prices for basic needs like gas, milk, bread, meet, school supplies, shoes, etc. Vrs the every looking threat of job security and prosperity, us worker dont know hen the last paycheck could or might come, so its becomes an evil cycle or save to get more, vrs cheap junk lasting......welcome to the new normal.

    How do we buy the better products, support local business, put enough food on the table for the family, pay the bills, save for college, save for retirement, have a nest egg for rainy days, and still have extra money for the fun things in life.......if you know the answer please share...lol

    Here's an example of why the assumption that "China builds junk" is foolhardy... China invests in future infrastructure instead of running around complaining the world is not like 1955 anymore. As an example, they lead the world in patents for high-speed train technology. We are rapidly falling behind in key tech areas because we are busy worry about who uses which bathroom and whether "Season's Greetings" is an assault on our freedom.


    World's speediest 600 km/h maglev rolls off assembly line in E.China’s Qingdao

    China's self-developed and the world's fastest maglev transportation system with a speed of 600 kilometers per hour rolled off the assembly line on Tuesday in Qingdao, East China's Shandong Province, marking another crucial milestone in the country's rapid rise as a global leader in high-speed rail technology and manufacturing and in its broad, ambitious goals to accelerate urbanization and build a modern socialist power.

    The maglev train can fill the gap between the current high-speed train that runs at around 350 km/h and airplanes with a speed of 800 km/h, which will support China's comprehensive transportation network planned by 2035, analysts noted.

    The maglev train is currently the fastest available ground vehicle. It is the fastest method of surface transportation within the range of 1,500 kilometers, according to a report by the CRRC sent to the Global Times on Tuesday. What is currently a 10-hour high-speed train trip from South China's Shenzhen to Shanghai will be shortened to only 2.5 hours once a maglev train is built.

    The new maglev train showcases a number of technological breakthroughs and advances, including a self-developed brake system that is 30 percent more efficient than the Shanghai maglev train, which means that the braking distance is reduced from about 16 kilometers to 10 kilometers, CRRC Qingdao Sifang Rolling Stock Research Institute (CRRC SRI) told the Global Times on Tuesday.

    CRRC SRI provides the braking system, coupler, anti-vibration system, electricity system, passenger information system (PIS) and other core components of the 600 km/h maglev train.

    CRRC technicians spent 19 months developing the magnetic poles for whirlpool brakes on the maglev train, which can be recycled in an -25 C to 170 C environment and can withstand vibrations.

    Its power supply system is one of the key systems of the high-speed maglev train, which plays an important role in the safe operation of the train. When the speed exceeds 100 km/h, a non-contact power supply is adopted. The train receiver system developed by CRRC SRI has good environmental adaptability and can work smoothly from -25 C to 45 C, CRRC SRI said.

    Researchers developed an articulated coupler for the train by using forged aluminum alloys as the key structural part, which ensured that the relative motion between the train cars is less than 1 millimeter, Jiang Yulong, the project leader of coupler at CRRC SRI, told the Global Times.

    The coupler length is only 280 millimeters, and weighs less than 30 kilograms, which meets the extremely spatial requirements of the maglev train, Jiang introduced.

    To guarantee smooth telecommunication during a high-speed run, 5G is reserved for the Wi-Fi system, and passengers will be able to charge their mobile phones wirelessly.

    The maglev project started in October 2016, with a prototype vehicle successfully developed in 2019 and making a trial run in June 2020. After system optimization, the final technical set was determined in January, and the complete system then started a six-month test, according to CRRC.

    The maglev train can be configured from 2 to 10 cars, each capable of accommodating more than 100 passengers, to meet different needs.

    "The 600 km/h high speed maglev transportation system means that the complete set of high-speed maglev train technologies is further mature and closer to the commercial landing. The realization of fully independent and controllable technologies can significantly reduce the cost of technological application, and will facilitate large-scale application," Zhang Xiaoxing, a lecturer of the School of Architecture at the South China University of Technology, told the Global Times on Tuesday.

    Shanghai, China's financial hub, is the only Chinese city operating a commercial high-speed maglev line, with a top speed of 430 km per hour. The Shanghai maglev train using German technology has been in operation since 2003, linking downtown Shanghai to the city's Pudong airport.

    By the end of 2020, the total length of China's railways was 146,300 kilometers, with the total mileage of the high-speed railway network at 38,000 kilometers, according to National Railway Administration data.

    China has the largest network of high-speed railways in the world, covering 95 percent of cities with a population of more than a million, according to the Ministry of Transport.

    China aims to build 200,000 kilometers of railways, 460,000 kilometers of highways, and 25,000 kilometers of high-level sea lanes by 2035, according to a 15-year transport expansion guideline published in February this year.

    The network is designed to support the "National 123" transportation circle, which stands for one-hour commute within the city, two-hour trip between city clusters, and three-hour travel to major cities nationwide, read the plan.

    Lu Huapu, director of the Transportation Research Institute of Tsinghua University, told the Global Times that the development of the high-speed transportation system helps China realize the "National 123 transportation circle," which was proposed in the national guideline.

    The maglev transportation system can greatly improve the quality and efficiency of transportation and change the characteristics of economic and geographical location and regional competitiveness, Lu said.

    The system will also help consolidate China's leading position in high-speed rail technology and is of great significance to promote the development and upgrading of related industries, analysts said.

    In global maglev train-related patents, China is first in terms of the accumulated number of patent applications by 2021, accounting for 43.52 percent, significantly higher than the 20.57 percent of Japan which took the second place, according to a report sent to the Global Times on Tuesday by PatSnap, an intelligent property data service provider.

    Japan's patents focus on the research and development of superconducting materials and basic science, while China's patents focused more on practice, including permanent magnets, rail beams, traffic engineering and suspension frame, per the PatSnap report.

    The 600 km/h high-speed maglev transportation system will be more likely first used in Guangzhou-Shenzhen-Hong Kong and Shanghai-Hangzhou high-speed maglev channels, as the high-quality development of core cities and town clusters along the routes is the decisive factor, said Zhang.

    But Zhao Jian, a professor with Beijing Jiaotong University, said that it is unlikely to export China's maglev train and relevant technologies in the near future, as other countries lack the scale to make the maglev lines profitable.

    "The maglev lines can earn money only when a network of high-speed transportation is formed, with huge passenger flows," Zhao told the Global Times on Tuesday.

    TexasT Texas, where are you from

    If you want Americans to under stand we need it in miles per hour. Kilometers is something our Canadian friends measure in.

    A km is about 6 /10 of a mile. So for a quick guesstimate I times the km by 6 and add a decimal point.

    600 km × 6 = 360.0 miles

    LOL True!
    In my USS Cod post, theres a foreign guy quoting the dimensions IN METRIC!! The Cod is a US boat!
    Anywho, being half my family is Canadian, I was introduced to the Metric system @ 11 or 12 y/o being we went to North Bay Ontario for summer vacation every summer to visit my Moms family, GREAT TIMES!
    I remember my Aunt's boss, the publisher for the North Bay Nugget had a new 1975 Buick Park Ave, 4 door, Black, red velour pillow interior, center console, cloth on EVERYTHING!
    Around '76 or '77 I remember seeing those dime sized clear vinyl stick on numbers to convert miles per hour to kilometers per hour on his speedo.
    My uncle Jack told me to convert a kilometer to a mile (roughly) multiply by .6 so 100 kmh is 60 mph, 80 kmh is 48/50 mph, 70 kmh is 40/42 mph.
    Temp is double and add 30/32 for a rough approximation.
    I do raz on my cousin's tho for ZED, Zed 28, 280 Zed, 300 Zed.
    Z is a letter, not a word:p
    Eve's troughs, Americans call 'em gutters.
    I remember my cousin Jason telling me " Im replacing my grandpas eve troughs" I said "oh you mean the gutters" Jason points to the ditch "THATS a gutter" LMAO
    Sofa, or couch, to them its a Chesterfieldo_Oo_O
    I love them Canadians, they have good beer!

    I’ve noticed that!
    Another thing I didn’t realize is some of the components in the “solid state” electronics DO wear out, capacitors mostly.
    I watch a lot of Mr Carlsons lab on you tube, he’s an electrical wizard! He’s Canadian too, he says “zed” also, lolol

    My US-made compound sheet metal cutters. They are stamped Bartlett Mfg Co. Detroit Michigan. Patented October 1909 and then another date which I presume is the date of manufacture - Nov 30, 1909.
    I have a total of five sheet metal cutters/pliers. This is my go to pair.

    I have a set of full-range Pioneer speakers that have 16" woofers that I bought at least 30 years ago. They still sound great. I think that in their price range they were hard to beat.
