Richtige Fernseher haben Röhren!

In Brief: On this site you will find pictures and information about some of the electronic, electrical and electrotechnical technology relics that the Frank Sharp Private museum has accumulated over the years .

Premise: There are lots of vintage electrical and electronic items that have not survived well or even completely disappeared and forgotten.

Or are not being collected nowadays in proportion to their significance or prevalence in their heyday, this is bad and the main part of the death land. The heavy, ugly sarcophagus; models with few endearing qualities, devices that have some over-riding disadvantage to ownership such as heavy weight,toxicity or inflated value when dismantled, tend to be under-represented by all but the most comprehensive collections and museums. They get relegated to the bottom of the wants list, derided as 'more trouble than they are worth', or just forgotten entirely. As a result, I started to notice gaps in the current representation of the history of electronic and electrical technology to the interested member of the public.


Following this idea around a bit, convinced me that a collection of the peculiar alone could not hope to survive on its own merits, but a museum that gave equal display space to the popular and the unpopular, would bring things to the attention of the average person that he has previously passed by or been shielded from. It's a matter of culture. From this, the Obsolete Technology Tellye Web Museum concept developed and all my other things too. It's an open platform for all electrical Electronic TV technology to have its few, but NOT last, moments of fame in a working, hand-on environment. We'll never own Colossus or Faraday's first transformer, but I can show things that you can't see at the Science Museum, and let you play with things that the Smithsonian can't allow people to touch, because my remit is different.

There was a society once that was the polar opposite of our disposable, junk society. A whole nation was built on the idea of placing quality before quantity in all things. The goal was not “more and newer,” but “better and higher" .This attitude was reflected not only in the manufacturing of material goods, but also in the realms of art and architecture, as well as in the social fabric of everyday life. The goal was for each new cohort of children to stand on a higher level than the preceding cohort: they were to be healthier, stronger, more intelligent, and more vibrant in every way.

The society that prioritized human, social and material quality is a Winner. Truly, it is the high point of all Western civilization. Consequently, its defeat meant the defeat of civilization itself.

Today, the West is headed for the abyss. For the ultimate fate of our disposable society is for that society itself to be disposed of. And this will happen sooner, rather than later.

OLD, but ORIGINAL, Well made, Funny, Not remotely controlled............. and not Made in CHINA.

Every CRT Television saved let revive knowledge, thoughts, moments of the past life which will never return again.........

Many contemporary "televisions" (more correctly named as displays) would not have this level of staying power, many would ware out or require major services within just five years or less and of course, there is that perennial bug bear of planned obsolescence where components are deliberately designed to fail and, or manufactured with limited edition specificities..... and without considering........picture......sound........quality........

..............The bitterness of poor quality is remembered long after the sweetness of todays funny gadgets low price has faded from memory........ . . . . . .....
Don't forget the past, the end of the world is upon us! Pretty soon it will all turn to dust!

Have big FUN ! !

  1. In the woods behind our house is a days-gone-by dumping ground. Old gas tanks, water heaters, mason jars, concrete blocks…whatever people couldn't or wouldn't haul off, it's there. And amongst all that crap is a totally intact old glass TV screen! The glass "funnel" on the back is broken off about 3 or 4 inches from the back of the screen itself. Otherwise, it's in great shape! It looks like a giant headlamp with rounded edges and it took me a while to figure out what it is (or was, I should say). My point is…I want to use it for a conversation piece, or art, or "something". But I don't know if it contains any dangerous chemicals/materials…or what to convert it to. Any advice is much appreciated!

  2. Hi, What you're referring in your description is (Was since it's broken neck) the CRT Tube which contains chemical compounds at various levels to obtain the internal phospor screen layer.

    Aluminized screen may refer to a type of cathode ray tube (CRT) for video display, television picture tubes,and it includes a thin layer of aluminium deposited on the back surface of their internal phosphor screen coating. Light from an excited area of the phosphor which would otherwise wastefully shine back into the tube is instead reflected forward through the phosphor coating, increasing the total visible light output. The aluminium layer must be thick enough to reflect light efficiently, yet not so thick as to absorb too great a proportion of the electron beam that excites the phosphor.

    CRTs may contain toxic phosphors, NEVER touch a CRT’s phosphor coating; it is extremely toxic. If you break a CRT, clean up the glass fragments very carefully. If you touch the phosphor, seek medical attention immediately.

    Older color and monochrome CRTs may contain toxic substances, such as cadmium, in the phosphors,the rear glass tube of modern CRTs may be made from leaded glass, which represent an environmental hazard if disposed of.

    CRTs are disposed of either by shipping them back to the manufacturer or by discarding them locally according to local recycling law / rules / places. If you ship a CRT back to the manufacturer, put it in the shipping container intact. If you dispose of a CRT locally, follow the procedure prescribed by your safety officer.

    I'm not understanding the exact target which you intend to go for, relating it to this Tv you've found.........

    Try to restore it or if better donate the rest of it to people who does restoring , recovering it for parts / components safely.

    If you intend to rescue the cabinet for display purpose then remove the internals and remove safely the CRT, but would be better if you let it do by a qualified / experienced person if you feel unsafe.



    FRANK.
