By the time you've built a half dozen 'classic' circuits from layouts like Doug's and debugged, tweaked, and modded them you don't need a net anymore. You should be capable of taking any schematic, or your own design, and developing your own layout. Many of the amps built by members here are exactly that.
As stated by the knowedgable individuals that posted above me, the basic building blocks, for nearly any tube amp design are found in the classics. Doug has provided all you need to master the classic circuits, plus a few tricks, plus how to troubleshoot problems, plus how to service amps, and much much more.
If you can come up with a schematic of what you want to build, you should be set. If you need help, everyone here will do what we can.

True, there are only so many classic circuits, but the number of variations on them is endless.
If you notice, many of the amps built by the members here are based on classics, but changed in some small way to season the flavor of it to the builder's taste.
There is probably not much that can't be done by combining features from existing amps.
That dosen't mean I am against inovation, though.

Why would you want to just depend on someone else to design the circuit, come up with the correct layout, build the board and send you all the correct parts in a baggie? Ok for the first amp or two. There are lots of people in Asia that just put parts in boards but I would hardly call that building an amp. I would tell someone just getting started in this hobby to learn the safety rules, clone a Champ, build an AB763, then start thinking, and experimenting. Dont be afraid to try something new and/or different. Take some initiative. The worst that can happen is it won't work. Even then some knowledge has been gained and you're ready for the next idea.
Sorry for the rant, but that's the way see things.

An example of what Leslie (Zachsdad) said:
A few months ago I designed a Super Single Ended amp (dubbed the "Howlin' Wolf"). It had all sorts of weird ideas I wanted to try.
To make a long story short....it sucked.
BUT.....In the process of working thru the bugs of that design, I learned much about what it takes to design a circuit and the factors that need to be taken into consideration. I am now more confident in my amp building/tweeking, and that chassis has become my "test bed" for new ideas (the latest of which is a fixed bias 2xEL84 unit with a Tweed style preamp).

Oh, sorry guys. I thought most of the people on here were Americans. Elegant minimalism is more of a sissy european thing. Americans generally want things bigger and badder and new and improved. It's a cultural thing, you probably wouldn't understand. Don't worry, we'll still win your wars for you though.
Ok, I understand that there is nothing new under the sun when it comes to the physics of how a sound is distorted and amplified through a tube circuit. But even you hardcore guys who can see how the circuits work in your head have to have been impressed when someone put in a switch to run tubes in two different modes, or when boogie or soldano came along and made a crushing sound by running things into each other. Sure, you could've done that, but you *didn't*. And they did.
And there is a whole other issue that I've tried to explained to people on this board before. I am even proud to say that I have warranted a "don't tell me how to run my business" flame from old man EL34 himself.
For every one of you smart guys there are ten schlumps like me. I have three kids under three and run my own business. Maybe a few hours I week I can sit with my kids at my feet and solder stuff together. And when I finish maybe I'll play the amp a dozen times before they put me in my custom pine box. It's not about tone for me, or elegant or classic. It's a nifty hobby with alot of brain food and a really high quality discussion board of yet more brain food in between diapers and email.
And a big factor in this, and why I ask the question in the first place, is that us schlumps are good customers and spend a ton of money. I don't poke around on this board looking for people to help me beat the costs of building amps. I've ordered several boards from people on Doug's official list and plan to build every one of them into a completed amp buying parts almost entirely from Doug. I find his approach head and shoulders above the big name in this industry and I plan to keep my business here.
I'd just like to build other stuff. I've never been a big fender fan to begin with, and the interworkings of the electronics I find as enjoyable as the sounds that come out of the amps. I want to build a triple rec. I want to build this crazy 30th anniversary. And while I have other quirky things I want to build, like this Kaeger thing that is like a power soak but doesn't seem to hurt amps, most of the stuff I want to build is mainstream and there are oodles of people who would really love to just buy the stuff on the parts list and put it together. How tough is it for you guys to template a board, make a layout diagram and give me a parts list, or even better, a shopping cart item with all the parts (this is the point where the EL34 flame came last time)?
I understand the very giving "don't worry, we'll help you do whatever you want". But I'm not a socialist. I'm a capitalist. I'd rather pay you to make me a board because getting into a shop to drill stuff for an hour or more isn't even possible for me right now. If I pay you for your time, which I consider as valueable as my own, then I have much less of a problem asking you a stupid question later. This is America. Pretend I'm a high paid consultant telling you how to exploit a niche market with little or no risk.
Ok, I'm ready this time. Let me get my gloves on.

Trying,
Not trying to pick a fight here just, giving you my opinion on you original Q, which at this point I dont know if I got right.
Why doesnt Doug sell every amp design created?
- not to poke fun, but this is a silly Q, especially after you state your a capitalist and not a socialist. If I was in Doug's head I could probably guess 2 reasons, money and becuase he is confident in the select product he sells.
Im also an American, who is looking to build something smaller and fuller, and I really dont understand how this plays into the question you put forth.

I think I took the opening lines of your post with the humor they were written in. In the same spirit, I'll mention that I recently completed my enlistment in the U.S. Navy.
If you contact the builders on Doug's recommended list, I'd bet at least some would be happy to provide a board for any amp you might want to build. I used to be one of the builders on that list, and occasioanlly fielded requests for something other than the standard boards. Eventually, I shied away from it, because a lot of people e-mailed with requests that turned out to be "kicking the tires" even though they didn't realize it at the time. And coming up with the new layout is often extremely time consuming, because now you have to find the right chassis, transformers, etc. to mate with the circuit board. Aftre the first few time of wasting days of production time creating new boards with no return, I eventually just fell back to the standard boards. And at the time, I was active duty military, and so my limited free time wasn't worth having only 1 or 2 extra boards sold.
If I remember, that was what Doug had said about the same issue. The board models offered filled the vast majority of requests, and there just wasn't enough interest for other models. There will always be some people interested in building their own Mesa-style amp. My point earlier was that Mesa amps are not that far from the Fender amps they evolved from origianally, and so it is possible to take a Fender or whatever with the same number of tubes, and mod it into a Mesa or beyond. That's why you see the threads about modding stock circuits.
The other problem is copying someone's patented circuit, and selling it. If you build a patented circuit for your own use, nobody will bother you. If you build it and offer it for sale, you're guilty of patent infringement and are open to legal hassles. So I could tell you how to mod an amp into anything ever offered by Mesa or any other company, but I can't sell you a ready-to-build kit for it (anyone remember the Dumble sh*tstorm a while back?).
Again, my view is that there aren't that many different options that can be taken with each part of an amp, and that by selecting how those options are employed in an amp, you can radically change the tone of the amp and its capabilities.
