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 ! !

The Quintrix CRTs:
Panasonic reintroduced its Quintrix picture tube technology, first launched in the Seventies, in Europe in 1996. The technology was initially used in 25 and 32in. CRTs. in 1997 year there were plans to adopt it for a much wider range, from 21in. to a mighty 36in. widescreen tube (Quintrix Wide). Quintrix employs a number of technical features that contribute to improved picture quality. One of these is specially treated pigmentation for the red and blue phosphors. As a result, ambient light of the same colour is reflected while ambient light of other colours is absorbed, giving a fifteen per cent contrast improvement. In addition, red and blue phosphors with EBU (European Broadcasting Union) colour points have been introduced. These were normally used only in broadcast monitors, and have a higher colour purity. Quintrix 4:3 aspect ratio tubes employ a Quadrupole In -line Gun (QIG) and a coma -free deflection yoke to give a twenty per cent increase in picture sharpness. The QIG has a redesigned first grid aperture of rectangular instead of circular shape and an extra grid to provide an additional pre -focus lens, see Fig. 1
. As a result, the vertical beam size at higher currents is reduced, giving improved focusing at the edges of the screen. The coma -free deflection yoke is used to reduce an effect known as spot -coma aberration. This is caused by the basic barrel -shaped deflection field distorting the beams produced by the two side guns, so that the vertical spot size produced by the red and blue beams is greater than the size of the centre, green spot. The coma - free system uses coma -correction elements to introduce pincushion correction to the deflection field, see Fig. 2. This compensation equalises the size of the three beams, reducing red and blue blur. There is an overall 10% resolution improvement. Quintrix tubes also use new bimetal thermal compensation springs to hold the shadowmask, reducing movement by 75 per cent in comparison with a conventional CRT.

A magnetic shield fixed within the CRT is used to reduce electron beam movement caused by the Earth's magnetic field. According to Panasonic this feature reduces the beam movement by 50 per cent. Quintrix Wide (16:9 aspect ratio) tubes use an Over - Lapping Field (OLF) electron gun. With this arrangement (see Fig. 3) the diameter of the main focusing lens is increased to 7.9mm in comparison with the 4.5mm of the three separate lenses in a conventional in -line gun tube. As a result, the electron beams fill a greater screen area with sharper focusing. The 36in. Super Flat Quintrix Widescreen TV set on display was an impressive -looking beast. Its CRT has a dot pitch of 0.7mm, the same as that was used in Panasonic's 1,125 -line Hi -Vision HD -TV sets in Japan. The CRT alone weighs 55kg - the set needs four people to lift it!
Three scart connectors are provided, plus RF, composite video and phono audio sockets. The set has been launched later 1997 , but no price information was available.........
