On contributions.

Is everyone OBLIGED to make contributions here? If one is here to learn, it can hardly be expected, or called reasonable.

Not to mention that this would soon stop being a DIY forum and turn into "recognized designer forum", kind of missing the point outlined in its very name.

As things stand, I am happy to report that I for one have been freely offered and duly delivered some very helpful assistance from some forum members. Including John. Isn't that the point?

I took some of that advice and was the better for it. Some I did not take for various reasons, even if I did see the virtue of it, because I think I can do just as well, or thereabouts, in a way which is more comfortable and practical to me.

I do NOT understand this need to knock anybody for any reason. What's the point, other than "proving" that one is smarter than "they"? If one agrees, fine, if not, start a discussion with facts, not insinuations. No-one is obliged to agree and/or accept anything on blind faith, but neither are we oblged to accept anyone's word on blind faith either.

As a true amateur, you might consider treating those who actually made real contributions to the art with a bit more respect and try to learn from them. Even if this means you have to drop preconceived notions, which btw is typically a part of learning.

Actually, most of us start from preconcieved notions, because there's tons of it waiting for the novice out there. Most never get past them, some eventually start to question them.

The first group are the mindless consumer mass who still buys into the notion that lower THD means better sound.

The second group usually gets into DIY, and, with a bit of luck and some help from their friends, eventually makes something worth the time and trouble.

Marce, I offer a 5 year warranty with my products. Yet, Wima, whose caps I use, gives me a warranty of only 3 months.

You tell me, exactly how could I stick my neck out for the lifetime of the products? How do I foretell which part might give up the ghost tomorrow?

In 1964, my late mom purchased a sewing machine, Necchi of Italy, and received a lifetime warranty on it. She passed on in 2005, so that warranty was actually good for 41 years, a commendable result.

But that was then, now they make sure it doesn't last too long, because if it does, what will their factories do?

I wasn't referring to every product out there, just certain products (rather expensive ones such as professional camera lenses) where there often was a lifetime guarantee, now there are only 10-15 year. For most commercial hand help/home electronics this isn't a problem any more because instead of buying something for life, now for some a phone is out of fashion after 6 months so its time to renew, keeps the factories going and the waste building up, and the marketing teams working (hooray!) a consumer society:crazy:

You reckon they need more than three production facilities ?

(One is situated in the largest industrial area of Germany, the Rhein-Ruhrgebiet. Second one in the north of Germany, 15 miles from the German-Dutch border. Third one is on the east side, in Berlin)

If the question was put to me, I really don't know.

However, if the Far East has started using them en masse, I would imagine economic sense would find it useful to have a manufacturing facility as near to your cistomers as possible. That way, you can react to their needs faster and you cut down on transportation costs, plus you make life more difficult for copycats.

If the Far East starts using them en masse, they will quickly figure out how to make the necessary parts themselves. Showing them how to do it will only accelerate the process.
