If I have the time and already have the parts on hand, why do you care?

Caution Kyle,
No telling how good the stock lead out wire is !!!!! Have fun. The trannies have to break in 200 hours.
I've done this on Hammond Ef XFRs to DHTs starting back in 2007 as I recall.
I "giggle" when these guys are so wrong. The bigger the EE degree, the worse the mind is open to new possibilities. Sad, sad. NONE of them would think to simply try it out and find out for themselves...ohhh no !!

That makes no sense at all if you stop to consider that statement.The EE has at least a four year education past high school. True EE programs vs the newer ET programs still require substantial credits in liberal arts. History, philosophy, language - just check and university degree outline.
On the strict technical side, the EE has studied many engineering theories, not just electrical but basic engineering principles that cover all engineering disciplines. Did you ever look at the study guide of a PE test? The FE exam (the first step) is universal for any PE license, the same for electrical, mechanical, civil. That's because true engineering has common ties within mathematics.
Any engineering curriculum requires work. It's not some degree program you can just BS through like a degree in "fine arts".
Now how is that "closed minded"?
Let's look at the weekend hobbyist such as you who refuses to acknowledge proven and tested theories. Eschews any attempt to test and qualify claims they make. States things like audio is extreme bandwidth which no modern test equipment can measure.
Now that sounds very "closed minded" in my book!

Unfortunately I have to take Jeff's side on this one. I did engineering and engineering related work for 27 years and while I have moved on to another field, it doesn't mean I don't remember the practical aspects.
My experience taught me that just because a person has the education and has worked in a capacity for a period of time doesn't make him the equal of all in that area of expertise. Engineers are like anyone else, there are great ones and sh*tty ones. More sh*tty than great in my experience.
I worked with a lot of engineers over the years that weren't worth a damn in practical matters. They could spout off endless calculations and what their profs told them were best practices but when it came down to the actual project decisions they were at a loss. This is in industries as diverse as robotics, aircraft design, underground mining vehicles and refineries. There is just no substitute for experience and if you think that's not the case, you're likely a pencil pushing desk jockey with no real practical experience.
So, bottom line, while I disagree with Jeff most of the time I also appreciate his 30 plus years of actually making amplifiers. Lots of them. I read about his projects in Sound Practices in the 90's and they weren't my style then or now but I give credit where it's due. He's done the real work to have an opinion and I'll support his right to have that opinion.
I certainly think that many posters here haven't got the hours in with a soldering iron to challenge what he thinks he hears and are just reciting Crowhurst or Jones or whoever they relate to. While I'm a bit short of Jeff's hours, I have made a large number of amps and preamps of a wide variety of designs and not all of them sucked. Many of them would be ridiculed by the so called experts here because I didn't follow your idol's path. I'm good with that. You should be too.
I know exactly the class of engineer you are referring to. Bookworms that can recite the most complex formulas but can't solder on a RCA connector. Then there are just plain incompetent engineers that can't do the theory or practical right.Then we also have the non degreed engineers that can run rings around the group. I know many of these types too and they are all very successful.
Myself, I am hardly an engineering scholar, I am not a born student at all. But I have been building electronic projects since I was about 9 years old, that would be 1969. I built a B&W TV camera from raw parts in my junior high school year when I was given an old vidicon tube. I made it color in my senior year when I got another one tube and deflection coil and with the help of the defunct Edmund Scientific made a red/cyan optical system.
But after entering Drexel in the late 70s, and that camera project got me in by the way, not my pitiful SATs, I soon learned how it worked in great detail and why many things I "TRIED" did not. At 54 years old I have built thousands of personal projects as well and many commercial projects and products in the broadcast television industry.
So you can see I for one am not impressed with JM's meger project history. For all that time he has advanced very little in understanding how this stuff works. And for him to insult the the industry professionals as a whole is what labels him an idiot!

"I certainly think that many posters here haven't got the hours in with a soldering iron to challenge what he thinks he hears..."
That is the problem. I'm sure he sincerely thinks he hears the effects of his choke mutilations. Just like the people on the Tweaker's Forum sincerely think they hear the effects of the crystals in the room, or the flashings LEDs, or the quantum fuses. It is all delusional.

Jeff, there is no doubt you have many years of building experience which few others can legitimately challenge. If one of us wanted something built and could afford to pay an expert to do it, I'm sure you would be a safe bet (provided that you were prepared to undertake the work). Some EEs, professionally qualified or otherwise, would not have the skills, experience, enthusiasm or understanding to be able to match your ability. You have also often given generous assistance to others and helped them achieve what they aimed for.
However, there are many EEs in this forum, both formally qualified and otherwise, who do understand what is going on -- because of their education, training and experience, not in spite of it -- and are very well able to contribute far more than most here. These members of AA, some of whom you know, deserve our credit and respect. They are far from being closed-minded and to dismiss them with such silly phrases is unprofessional, unfair and just plain wrong.
