Want to build an amp

Why don't you learn how to use Google, Jerk.

How about one of these?

I built one a few years ago and have been happy with it. It's all the power I could ever need.

Aiwa did something similar to this years back, when they had the supply rails to the output stages switched 'on the fly' by FETs, according to the demands of power. There was then a very sophisticated protection circuit, which monitored many things, including output current.

And it it's not a repair issue, the post doesn't belong here.

This is sci.electronics.repair, not something else.

Read Mark Zenier's guide to the sci.electronics.* hierarchy ftp://ftp.eskimo.com/u/m/mzenier/seguide9706.txt and post in the proper place instead of adding to the decline of this newsgroup.

Apart from the obvious spam posts, which almost all groups suffer from, and is by no means the fault of the posters here, I see nothing that constitutes the spiralling decline that you are always bleating on about as occuring to this group. I have been active on it for some years now, and it seems to me that little has changed. Most questions still get answered in a polite and gentlemanly way. Most posters' problems are resolved by the regular posters, much as on other groups. I don't see anything in the guide that you have linked to, which seems to cover any kind of 'decline' that you perceive. You have a real bee in your bonnet about what you consider to be off-topic posting. As I have said to you before, sometimes people wander on here by accident with a question which, whilst being electronically related, is not necessarily to do with repair, but never-the-less is still an interesting discussion point. Sometimes, regular posters, who regularly help out with other people's problems, (such as ZZ who started this thread) have a general electronics issue that they wish to discuss with other engineers who are their 'net friends'. Should they go off to some other group where they don't know anyone, just to please you ? Sometimes, real engineers just want to 'chat amongst themselves' about things in which they have a mutual interest, which may not be directly repair related. Provided that this takes place generally within existing threads, I don't see that it impacts on the validity of the group as being one primarily for repair topics, at all.

Just as a matter of interest, other than playing at usenet policeman, just what exactly do you consider your function on here to be ? I don't recall ever having seen you make a constructive repair reply to any poster. Do you even have an electronics repair background ? Your normal input is just to tell people that their post is unwelcome, and to clear off to a different group ...

Bingo! This is the heart of the matter. Nobody named 'Michael' has ever, TTBOMK, contributed anything of value to this forum. I myself have contributed damn little beyond anecdotal advice; but I have learned much from the masters here. That would not include Michael, whomever he is.

I suggest to him, that he get a life and quit trying to run others'.....

If you check Michael's profile, he has posted more than 14,000 times in the past couple of years to every single usenet group. The internet is his life, poor soul.

The original Poster did post a strange sort of message, but that's still no excuse for the kind of reply he received from Michael.

Your reply is not a repair issue. By your own logic it does not belong here either. Practice what you preach Netcop-Wannabe.

I didn't think that I had never contributed anything... I don't think I have contributed a lot since I'm not an electronics engineer, but every now and then I help answer easy questions that passer byes ask like whats wrong with my LCD monitor. :)

Well bozo, I've been reading this newsgroup since 1995. I can remember when it was loaded with posts about repair.

I read it to learn, and posted when I had something to contribute.

I've had enough posts here, and hey, there's even a snippet of one of mine in the FAQ.

But like so many other newsgroups, it's turning into a hangout for people who can't be bothered finding the right newsgroup.

The "proof" of someone's value to a newsgroup is not how many posts they make. Because some people with too much time on their hands decide they'll hang out in a newsgroup, and post all kinds of off-topic junk. They rack up massive posting history in that newsgroup (and too often don't post anywhere else), but they often don't have that much to say on topic.

The newsgroup becomes their hangout, and they don't care what the original intent of the newsgroup was.

The lack of on topic messages makes people tune out, the "regulars" don't notice, because they are too busy hanging out. Indeed, those "regulars" are likely shorter time posters than the people who leave.

And the fewer people who read a newsgroup means the fewer people who are around to reply when someone needs something. The pool of people who can answer is diminished. Just because a handful are oh so quick to respond to every post at any hour of the day does not mean they are the best people to answer all questions.

Someone who traced the linear/power supply board in the Mac Plus years ago won't be of much value when someone asks about it if they are no longer reading the newsgroup.

Some specific bit of knowledge may come up rarely, but the moment someone asks about that area, you'd better hope they are still reading the newsgroup.

If the hotshot "regulars" so badly want to answer every single post, then let them find the proper newsgroup.

When so much of the posting is off-topic, it's not really a surprise that I have nothing "worth" posting about.

While ironically, there is nothing much to post about in the proper place either, because they aren't getting the on-topic posts either.

I can remember when sci.electronics was split. "Too much traffic" some complaind about. It was rather brisk, but then I was using a 2400 baud modem and had no more than an hour a day access to the BBS where I was reading the newsgroups.

But what we have now is lots of newsgroups, and half the time people don't even post in the right place. I don't read .design any more because it became a hangout, the swaggering of the "regulars" who took over the newsgroup, who "decided" it was acceptable to post all kinds of junk. The fact that there is a lot of political junk in there is both a cause and effect, because they decided it was acceptable and then hey, one thing people fight about is politics. But then all kinds of beginners post there because "this has the most traffic".

Meanwhile, there is a perfectly good newsgroup for .basic posts, and it's pretty empty because nobody much is using it for its intended purpose. There's one about .components and it's underused, and so on. There area load and loads of newsgroups to discuss computers, and places to discuss vacuum tubes.

We might as well all fold into One Big Newsgroup if people can't be bothered to use the proper ones.

ANd hey, when idiots post in the wrong newsgroup, they hurt themselves. Any beginner who posts in .design is likely to get an answer that isn't useful to them. Someone who posts here about a computer problem is relying on someone incidentally having knowledge that can solve it. Find the right place, and you increase your chances of getting a useful answer.

Most of the newsgroups I read, I've read daily for over a decade. I've added some, a handful I've tuned into for a relatively short time, but most of the newsgroups I read today I was reading a decade ago. But increasingly I am tuning out. Not because of spam, not even because of the too often massive cross-posting. I don't tune out because there's no traffic (some get a handful of posts every few months).

No, I tune out when it becomes a hangout. People more interested in arguing among themselves than talking to each other. People bored with the purpose of the newsgroup, who still stick around instead of finding the proper place, so they post about the weather and politics and their computer problems and everything else.

And in each of those newsgroups, I have a "big enough" posting history. I also have a long enough reading history. But hey, it's dwarfed by the people who rack up thousands of messages in a few years, but much of which isn't on topic.

If I wanted to read general purpose newsgroups, I'd read the local newsgroup (which ironically I do, but it's not being used much).

Most people don't realize how a newsgroup declines, because they aren't paying attention. And by the time it is noticeable by many, it's too late.

Michael

I got an even bette idea. How about you go f*ck yourself?

the original poster has posted here several times and is well repected.

What have you posted here besides your bitching?

You know, if you had a valid point with respect to this particular group, I might be persuaded to go along with you, but over the years that I have 'hung out' on here as you so quaintly put it, I have seen no signs of any kind of general decline. In fact, I would go as far as to say that this newsgroup is a shining example of one that continues to exist for its primary purpose of helping people with their repair problems, and is absolutely the right place for anyone with a repair-related question. The vast majority of posts to this group - and there are a good number most days - are absolutely 'on-topic' by your very limited criteria, and get dealt with by one or many of the very good people who 'hang out' on here, and have a huge raft of both specialist and general electronic knowledge gained by a lifetime either as a professional or serious hobbyist.

I, and I'm sure many others who 'hang out' on here, resent your implication that we are internet saddos who live to jump on every post, and collect as many posting statistics as possible. I come on here, as part of my professional life, because I feel that 35 years of experience in the repair business, is worth offering to amateurs, hobbyists and less or differently experienced professional service engineers. I genuinely enjoy helping others, and I'm pretty sure that most of the other regulars on here, do as well. I also come here to continue to learn from others differently experienced from myself, as I'm certain many of the other regulars do.

If you are active in a useful way on all of the newsgroups that you claim, and you honestly believe that this one is in terminal decline, then perhaps you should just leave, as you keep threatening to do. Perhaps you should also stop and consider the old phrase "If things don't change, they'll stay as they are ..." Nothing in this world stands still. Everything evolves, and not always for what we might all consider to be the better. Usenet is no exception. There is now a much wider spectrum of people who know that Usenet exists, and have found out how to get access to it. That in itself changes the nature of the beast. Accept it. Get over it. Move with the times.

And if you can't, then really do consider departing to a group where there

That's right tough guy; Go Home and Cry.

Got that right. Go somewhere where theres a moderator so nobody can hurt your precious little feelings. Nobody wants you around here anyway you big baby.

I wonder what the moderators at that "form where all of the good techs are on" are going to if he posts a death threat like he did earlier in this thread?

I'm not worried one bit. I've seen this happen so many times over the years. He's just another one of those people that think they are so hard behind their anonymous computer screens and think they can kick anybody's ass but when they are actually about to get a smack across their face they threaten the other person with assult charges and lawsuits.

He might be able to build amplifiers and write operating systems and find a cure for AIDS but street smarts? Not likely.

Hey Fleetie ! Long time no hear from. Good to see you on here. How's it going ?
