Well, if its a kit then where the holes for where the transformers go should already be planned out for you, right? Otherwise, is it really a kit for beginners?
Again, go look at some of the list where I talked about kirchhoff. The list is only a brief start.
So how does one get this grained when never work on anything requiring attention?
Have you ever built or even worked on an engine? For example, if you are not watching your steps, you can forget to plastiguage and later wonder why have so little oil pressure. Or not toque something down. Just thought of a better example. Using a 1950s table saw with a small top cutting full size sheets of plywood. You bet I was paying full attention! The power switch was tiny and if a piece was on the top, couldn't be reached. But, I had been taught and I obeyed the rules (ex. no loose sleeves).
There is no kit for tube monoblocks, this has already been stated by others. This is why I asked about the complexity of stereo, I thought best to start out simple. Isn't that odd how folks want me to start simple then desire me to build something complex instead?
No. Some people with EE degrees don't design very good amplifiers. You need a certain about amplifier design expertise though, however you acquire it. You could try reading Bob Cordell's book, the Merlin Blencowe books, etc. But probably need to start at the beginning first before you can understand what is in the books.
Besides, I already told you the particular book that was recommended is pretty intuitive, as such books go. If you can't understand it, then you really do need to start at the beginning.
I understood the first time. Still don't know how this will determine the value of C8 and R16, weird how so many folks have built with this value (even with an OPT not meeting specification) and then rave about how good it sounds. This world is certainly illogical, so not expecting logic, just observing.
So far I been understanding, though off to find this information I must read before I can ask any questions or start building anything, even re-capping speaker crossovers.
You don't. its a numbers game. You improve your odds of survival quite a bit by forming proper habits is all.
Of course. At least you can see where danger is in way that is different from electrical danger. You can't see without a meter if a capacitor is charged.
This is all I found: "Okay. But, Kirchhoff's law is a simplified case of Maxwell's, so a discussion about when it is close enough may be subject to opinion. Conservation of charge is a more fundamental principle."
I already know who Maxwell is, though gets me no closer.
Nobody said it will. What it will do is allow you to start understanding closer to what you need to know to understand how the value of C8 and R16 can be determined. I told you this takes years. I told you that you need to start at the beginning rather than trying to bypass it. You want to jump right into 3rd year college engineering, or the equivalent knowledge learned outside of college. It isn't that hard, but you have learn things in steps.
The similarity is both you evaluate the dangers and go over and practice your movements.
My meter includes capacitance. However, at some point the capacitor will discharge if grounded, I know that. If I need to leave it a week to drain, well, by golly I will do that.
Now that jog my memory, I have worked on live 240VAC, checking capacitors.
You are not knowledgeable enough nor experienced enough to express such an opinion, nor to evaluate the validity of someone else's opinion on the subject. Look, we don't make things more complicated than they need to be or we would never get much done. A great deal can be done with Kirchoff Laws. Don't think you are above needing to learn them first.
Darn it, can you answer the blasted question without changing the answer back and forth? Either the the OPT works with the schematic or it doesn't, I know it can't be both. We both know the specification, I provided a plethora of options that met the Z specification so C8 and R16 could remain the same values.
Now if gone back to the answer being the schematic is incorrect, then clearly because of your generous help know need to select something different. Again, thank you! 🙂
Thank you for the laugh, I was just starting to get a smidge tense. 🤣
Or was it not a joke and didn't see the quote marks?
"Either the the OPT works with the schematic or it doesn't..."
You think? Its not that simple. Maybe it works with some speakers and speaker cables and when you change to different speaker cables then the amplifier burns up. Its happened. You are not yet prepared to study how that happens and how to prevent it.
EDIT: I can attach a paper on it, but what you get out of it will be limited. And there is more to know than what is in the paper.

I can only go by the information @grovergardner and you have told me.
So if so sensitive, then how does any manufacture sell an amplifier? Where in the amplifier specification does it state which speakers must be used?
@tomchr has a plethora of very satisfied customers using a wide range of speakers, yet, no amplifier has burned up.
Manufacturer's are supposed to know how to check for such things and fix them if need be. As it happens some manufacturers didn't know.
EDIT: Regarding tomchr, I have two of his headphone amps. Both measure very, very well. They are both backup amps today. They are not audibly perfect despite the PSS FFT measurements. They don't blow up with the wrong headphone cable, but Tom is a designer who knows about how to design for that. You don't.

That is not it. The statement you made was in response of a statement of yours I quoted and said I had made the statement myself.
Of course I wouldn't dare think to give an opinion on something I don't know. 😉
By the way, do you know if you highlight text it will pop up a black button that can be clicked on to do a quote? I happened on it by accident.
Still not understanding.
Let me say another way. Are you 100 percent certain Audio Note L1 will only work for certain speakers?
If so, then that is simple to resolve, choose speakers that work. That simple. Doesn't require learning how to cook a deadly Japanese fish. 😉 (To steal Richard's (@OldHector ) analogy.)
I have read the whole thread containing a number of builds and didn't see that mentioned.
