Nelson and I and thousands of other guys built amplifiers before the internet, before there were more than a few good books on the subject. Did I overlook something? Probably. Will it burn? Better try it outside first. Burn a month's spare-change a few times, "fear" gets less.

Finding this Forum and getting involved is what enabled me to build my first amp.
Nelson's articles and veterans of this forum were my enablers. If you're truly putting
forth the effort to learn - when you post a question for help, it will get answered.
Best thing that ever happened to me in my Audio Journey Thanks guys.

[ie: if an idiot like me can do it, so can you!]

Whenever I decide to build a new project, I spend days reading the thread on that project. Everytime I read something I think I will use during the build I copy the info and paste it to word document. I use all the info I collected as my cheat sheet while following 6L6 build guides or Tea-Bags guide, or anyone else I also have several documents for power supplies, matching fets etc.
I try to co!llect as much wisdom from the members here and copy the wisdom so I can continue to learn.
My doctor says this is a great way to keep dementia away, is to learn and use reasoning to solve problems. When I'm totally lost, I just ask a question.

I agree with elwood.

One thing that is hard for non professionals in the trade is that hardly a new project here comes without 5 revisions, and then 10 different people start arguing why a resistor X is much better than resistor Y. It gives you some food for thought, but also gets old quickly. The revisions are totally acceptable though. Nobody is being paid for work here, and almost nobody, except for Mr. Pass and a couple of others are actually professionals on the day-to-day life. Stuff goes wrong and must be fixed somehow.

I started to ignore most of the side discussions and adhering to what I think is important, which is mostly the original design and important revisions.

I appreciate the help of most in this forum. Unfortunately there is still a lot of "secrecy" from some members who like to show their low resolution pictures of something that is done but will not share why their system is so "marvelous". Usually saying it's trivial and obvious, details are not needed. Well, when you put together an electronics engineer with an audiophile, not much can be expected anyway! lol

I agree with the folks above, build your amp STOCK according to the 6L6 build guide and ask questions. Also study the schematic and how it relates to the physical circuit boards. In the past I've been guilty of soldering components on to a board without knowing where they are in the circuit or what they do.

Even sharing a Mouser BOM is not doable, since part numbers constantly go obsolete or out of stock.

One advantage of building stock is that you get something that is tried and
true and doesn't differ much from the original FW design. If you build it properly
it should work well.

I don't think a mouser cart with out of stock parts is necessarily a deal breaker,
especially if the builder takes the opportunity to learn to choose replacements.

I find the most helpful members are not at all secretive, except in cases where
an answer may involve privileged info/IP they cannot publicly disclose.

One thing I do wonder about is how easy/difficult it is to edit the build guide
that is in a thread, compared to a wiki article. I sometimes
see the same questions/issues pop up. Usually the answers are already in
the build guides, but perhaps these points can be further highlighted?

Anyway, I wish the OP success in his build.

Dennis

I have the habit of as I go through a thread of a build that I really want to tackle, where Q&A plus advice etc happens, I use the Snipping Tool, and save the relevant captures to a directory for the specific project. Pictures and schematics are also saved this way.
This gives me the chance to read through at my leisure, work things out, and if necessary come back and ask questions - which I often do. I've been a noob for many years now, but I'm slowly learning. Never looked at 'lectronics till 8 years ago. Still need to wrap my head around things. Though I did find NEETS and started learning this way too. And I'll be 59 one of these days.

Default Audiophile affirmative action?

There are 27 posts before this one, every one of which suggesting that my OP idea was not very good. The consensus of these 27 people was: Man up, pay your dues. If you get stuck, you will be helped and you will be richly rewarded for the effort.

If 27 people are saying your idea is nuts and nobody is agreeing with you, then maybe you should pay attention to the 27. But I'm a little bit stubborn, so I am going to try again, this time with an analogy:

Suppose you 27 guys are successful businessmen who have been invited back to your inner city high school to give the 10th graders some advice. Your advice is very consistent: stay in school, do your homework, work hard, get your degree, have a positive attitude, follow up on opportunities.

Now some kid comes along and says: That's great advice, and if I can follow it, I will certainly become a successful contributor to society. But, frankly, I don't know if I can follow that advice. I don't have decent nutrition, my dad beats me, my friends are putting immense social pressure on me not to follow your advice and I don't know if I'm inclined or able to resist the pressure.

Then you say: Well, I had all those problems, and look at me. I made it, so you can too.

And the kid says: I admire you for your set of virtues and that you made it, but you and I both know that 90% of the kids listening to you right now will not be able to follow your advice, even though they know it's good, solid advice.

So that is my analogy. You guys all made it through the mill, and if you can do it, anybody can do it. While that may be technically true, it ignores all the wannabe audiophiles who got left behind. I believe that many people would love to participate in this activity, but they are dissuaded or they drop out, perhaps because the learning curve is too steep. Don't women like beautiful-sounding music? But there are almost zero women in this open, welcoming, free-to-join club.

This hobby seems to generally attract technically-oriented, somewhat introverted, middle-aged males, which is fine. [I'm not talking about YOU, I'm saying generally] People with this profile become the Navy SEALS of the avocation. But you don't win a war just with SEALS. You need soldiers. Man, I'm pushing the analogies.

As Papa said, "it's entertainment, not dialysis". And that is certainly true for most of us. But what if, from your perspective, it looks a lot more like dialysis than entertainment? For those people, I think that a few changes could be made to reduce the dialysis quotient and increase their probability of success.

Many people also said, "Just follow the build guides, ignore the diversions." To which I respectfully reply: I believe you have forgotten what it's like to be a complete newby, particularly one who lacks your skills and background. Trust me. I could go through the build guide and BOM for just the power supply alone, step by step, point by point, and demonstrate overwhelmingly the amount of largely unnecessary and uneducational hardship that is involved in getting through that with no skills or experience. But I won't unless you insist.

Having said that, I'm going to do it. i'm going to take you up ln your generous offers of support and I will get it done, and I will be much the wiser for it. And, I will have a beautiful Aleph J to enjoy for the rest of my life. But I could have done it with a lot less dialysis, and a lot of people, I believe, could have done it also, wanted to do it, but chose to do something else that looked more like entertainment.

nobody said that you're wrong, quite contrary

most of replies are made as affirmative anecdotes, some are more serious ..... but let's try putting one stance in one or few sentences :

Take any of Hafler Kit Manuals, or - older ones - Dynaco; read them, and try to imagine how much time is invested in writing one........ even nowadays, with handy editing tools we all have, biggest investment is certainly intelectual

That can be justified only in case of hefty commercial article ........ and none of these (we are having here on mind) are commercial in that way , or amount

remember - nobody here is exactly paid for helping anyone ........ and that's main reason why I'm hanging here , always feeling warm around heart, just thinking how much people around invested energy and time to teach me, during all these years

(while being stupid, or just plainly good-mannered, to not see how little I learned )
