I have other things to write about.

I said it was useful. It would have been unhelpful and misleading of me not to qualify that recommendation. Do we have to separate everything into utter condemnation or sycophantic praise? What is wrong with fair criticism? Critical faculties are supposed to be a good thing.

Critical faculties are a good thing; in fact they're required for anyone to grow in knowledge and experience in any field. And the sooner constructive criticism is given, the less time wasted.

Not everyone knows how to criticize, nor how to handle criticism. But it is pretty simple ... if there is something wrong, say so. And if you (or I) are wrong, accept that we are wrong sometimes, learn, and move on.

It is not a crime to be a "teenager" who writes about what he knows or believes. But it is somewhat of a crime to let errors or hasty conclusions go without comment, so that people can learn from both his youthful ideas and what is really what.

I did not think the author of that paper would disagree. From the first page:
" ...
Many professional audio providers and audiophiles have mis-conceptions about how a solid state (transistor) amplifier functions. Mis-conceptions occur because basic principles are not understood.
..."

Pretty much what has been said in this thread already. And if the author truly believes what he has written there, he would not object to constructive criticism. However I see by reading it that he has already closed his mind to certain things. That is a mistake, and it betrays his opening statements.

To the OP:
It's an interesting read but definitely it would be a shame to consider it conclusive. If used as an introduction to electronics, maybe a decent start. But more advanced texts, well written to be easily understood, again as suggested in this thread, is a good idea (explaining what you know is far from easy when you have a good grasp of a subject; it's difficult to remember what it was like to not know, so you tend to assume people know things they do not, which confuses them).

Anyone who can convey special knowledge so the student quickly grasps the concept is a rare individual, and it's a great gift if someone points you in their direction. They are saving you time, money, grief and effort. Take advantage.

After reading it further, I have to revise my conclusions about the paper. It starts out reasonably well if a little narrow-minded and over-confident, but quickly deteriorates into pure opinion, and not well-founded opinion at that. It ends in a bizarre summary that the author should probably have kept to himself. I can ignore the politics but the electronics are too often just plain wrong.

The OP should maybe ignore it completely. Check out the other suggested texts.

I am pretty sure if you hired the author to build you a guitar amplifier, you would hate it, while at the same time he would insist it was perfect and demand full payment.

True. This thread is an example; people seem unable to handle criticism of what someone else wrote.

I never said it was. I find it interesting that factual errors and unsupported assertions in the original article are somehow regarded as less important than my use of the word 'teenager' to attempt to give the author the benefit of the doubt for factual and stylistic problems. Have I offended the Equality gods?

I have no idea who the author is and, as far as I am aware, he is not on this forum so it would be improper to give detailed criticism where he can't see it and respond. I have better things to do with my time anyway. Can I say again that the article, despite its problems, would be useful for a complete beginner. It is useful, it just isn't perfect.

Now you are being even more critical than me! Will you give us a detailed list of errors and corrections, as you demanded of me? Will people now queue up to criticise you, as they did me?

Let us drop the fruitless discussion of this article, and get back to the point of this thread. Otherwise I am out.

Hey guys!

DF96 is the forum member that helps people like no other.

Spend his time correcting mistakes.

There are days when his style is somewhat harsh, it is because he knows a lot and certainly some opinions bother him.

Those who know him, take their criticism with a different philosophy, and we can always learn something.

In the past we had differences, but believe me, he is a good man and is intended to help.

Take advantage of his advice and do not get angry.
