The interesting question is, how much of this bad old stuff was there? Well, considering that, according to Sturgeon's Law "90% of everything is crap" - I'd say about one item in ten wasn't. There is also the issue of "what it was made of". Stuff which rotted, regardless of quality, is more often lost than the tuff which doesn't. That's funny. Possibly true as well.

"Christopher Tidy" wrote in message ... But again, when modern TVs do break they're often impossible to repair. Don't confuse "impossible to repair" with "uneconomical to repair" They are two very different things. I can't prove it, but I have little doubt that most TVs are junked with fairly minor problems, easily repaired by someone with the proper skills and knowledge and with access to the proper parts and information. The problem is, even that simple repair would cost vaguely as much as a new TV. Therefore, TV repair shops (except for warranty service depots) are a dying breed. I'm not. Perhaps I didn't explain myself well enough, though. I'm particularly interested in what happens when spare parts are no longer available. My guess is that in the absence of spare parts, a modern TV will be impossible to repair, but an older TV may be repairable in the hands of a knowledgeable person. Best wishes, Chris |

The dryer I got at the same time was replaced a long time ago, after several big burnouts of the heating element. The fridge is still running, and shows no sign of trouble. I'm fairly impressed with that. Even the salesman said that the new washer would not likely last 29 years! Jon |

Easy enough with all point-to-point construction with terminal strips and tube sockets. Back then, the labor was still cheaper than the components. Actually it isn't mush worse than the early reflex radios where a single amplifer was used for different frequnncies. The same tube was an RF and AF amp at the same time. You didn't even get the basics like horizontal hold and vertical hold trimmers, unless a tech added them later to make the set work. By the time the parts had aged enough to need adjusted, it was out of warranty. The schematics are in the old H. W. Sams Photofacts collection. http://www.samswebsite.com/ None of the circuits would have ever passed a design review. Muntz omitted extra RF amplifier sections and most filtering, figuring the set was being sold in strong signal areas only - which probably led to the obscenely high power levels used by the TV Transmitters on Mount Wilson, where there is no permanent population other than the technicians. Those mountaintop sites covered a large area, and the back side was shielded by the mountain. There is no way they would build a higher power site so people could use cheap YVs. The electric bill was always the biggest expense at most commercial stations. There are still areas up there where the RF levels are so hot at ground level you can light a 4' fluorescent lamp just by taking it out of the Faraday Cage of your car trunk. One of those is gone. The okld VOA Bethany plant was so strong they could have lit everything with stray RF.

It's difficult to compare the two situations, I know, because the parts for the latest TVs are currently more plentiful. But would you rather be trying to fix a 1958 TV right now, or a 2008 TV in 2058? I'd go for the 1958 TV, because the electronics will be simpler with more discrete components, and so easier to understand. With many items of modern electronics, you're stuck unless you can get replacement circuit boards. I tried to fix a Sun computer power supply a while back, and it was a nightmare. I got it fixed for a month or two, but it was luck more than anything else. When it failed the second time, I just got another one. Best wishes, Chris |

But I've been thinking about this issue for some time, and would like to seek the opinion of people here. You frequently hear people complain about the quality of modern products and say things like "They don't make them like they used to". But it has occurred to me that maybe older products look good today because only the good products have stood the test of time, and the poor products have been thrown away years ago. What do people think? Were products better in general back in the fifties, say, or were there a mixture of good and bad? I'd be interested to hear people's opinions, as I'm not old enough to remember myself. Best wishes, Chris No problem. Some people here are so old that we can't remember, either. g It's a mixed bag. Cars are much better, and fishing reels are, too. But wooden matches have gone to hell. Toasters today are complete crap compared to the old ones. Most appliances are total crap nowadays. If you've moved a washer, dryer, or fridge since about the year 2000, you'd have noticed that they're about half the weight of their earlier counterparts; 1/3 the weight of '50s items (many of which are still kicking.) I'm always impressed when people keep their old appliances going. I think we should be proud of that kind of philosophy. Best wishes, Chris |

The table would reveal the cartesian location of the component on the circuit board (Say F-5). A cartesian grid was superimposed on a photograph of the circuit board in question. Letters IIRC were placed along the X axis and numbers IIRC along the Y axis. When you looked at the intersection of 'F' and '5' on the circuit board photograph, you could find component C329 in about a seconds time because your search area was so much smaller than that of the entire board. I used the same documentation technique for fasteners when I worked at a well known Cupertino California Computer manufacturer. I saw that an engineer using my documentation was able to quickly reassemble a notebook in the proper sequence with the proper fastener in the proper location. If you look at the Gerber file collection for a modern circuit board you will see a file that relates each component's reference designator to an XY offset from some corner fiducial. It's normally expressed in mils but still reduces location time greatly. What am I saying? It makes it *possible* to locate C329 in two minutes on a board that contains several thousand components. This, to me is the essence of cool. --Winston |

But wooden matches have gone to hell. I'm with you on all of that. I'd love to have a decent strike everywhere match. I suspect the problem is that they took all or most of the phosphorus out of the match tips, for safety. Phosphorus is poisonous, and can be really hard on unsupervised children. Joe Gwinn Partly correct. Elemental white phosphorus is more toxic than potassium cyanide (orally). But strike-anywhere matches have not contained white P for a long time. The tongue-twister tetraphosphorus trisulfide is one of the ingredients in the white tip. It provides friction sensitivity with low toxicity. Strangely enough, I was browsing in Stagers Store in Portage PA this summer, and saw a shelf that had SAW matches. Grabbed a pack of three boxes. They seem to work pretty well, though they have a tendency to break more easily than I remember from my youth (tasted an awful lot of sulfur dioxide while learning to strike a match on my teeth).

Possibly. I doubt if you can buy a new flyback coil, or even a CRT for a 70's television. Only a few types of tubes are manufactured these days, though lots of old tubes are still on the market. It's difficult to compare the two situations, I know, because the parts for the latest TVs are currently more plentiful. But would you rather be trying to fix a 1958 TV right now, or a 2008 TV in 2058? I'd go for the 1958 TV, because the electronics will be simpler with more discrete components, and so easier to understand. With many items of modern electronics, you're stuck unless you can get replacement circuit boards. I tried to fix a Sun computer power supply a while back, and it was a nightmare. I got it fixed for a month or two, but it was luck more than anything else. When it failed the second time, I just got another one. Best wishes, Chris I took a 12 year old 25" Zenith in to a local dealer for a free estimate when the pix went red. Got the estimate @ $50 the next day with the advise that the next time the colour went wonky I should leave it at the curb. Picked it up next day and it has worked fine for the last six months.

Not because they were inherently unrepairable, but because they were crap. There was no way a service shop could end up with a happy customer, so they learned not to try. You woud probably get the same reaction if you took your Yugo to your mechanic for a tune up. Yes on the Muntz. Don't know about the Yugo. Joe gwinn |

I know this is coming rather late in the thread, but can anyone think of
specific examples of older products that were junk? Many thanks, Chris |

Does the same thing happen in brick or wooden buildings under high voltage power lines in cities? I'm not sure that the "making use of wasted energy" claimed is correct, though. I have a suspicion that a field full of fluorescent tubes may draw more power from the lines than an empty field. Best wishes, Chris |

There was or still is a stretch of very high tension power lines in New Jersey
that handled 1 Million volts. It was a sight as we drove under them to visit Dad at Bell Labs. Near the end of a long trip and wondering what the heck. The area near the lines were bare of all living plants. Not any grass. The High voltage produced long lines of purple light about each of the three phases. It was a test line being tested in the field. Thought of the national grid... Electric field will excite gas - simply by adding energy to an electron - it raising in a new quanta shell for a while and then when least expected (uncertainly principle) fall from this elevated shell and return to the normal level, giving off a frequency of light proportional to that of the change in radius. Nitrogen is purplish. Neon is orangish and is busted to red-orange by other chemicals. The whole issue is to add energy to the atom within. RF or Heat or AF. Martin Martin H.
