Gee, lets see... How about better sounding than any commercial product that is within 10 times the cost. I'd think that is fantastic. This amp can be that good if done right.

Is one of your teaching goales to show a very odd way to draw a schematic ?

At least in my opinion one should be able to do without splitting such a simple circuit in half....

If you cant figure out how it goes together then you should not be allowed to play with electricty.

Ooh I do know how to put it together all right.

It's just that if you want that someone can use it as a learning experiance then it is made too complicated for a beginner DIY person. One would most likely drop the analysis because you first have to figure out how the schematics is built up before you can do any analysis on it... in my opinion it's a wrong way to teach amp design.

Actually I would put the VA stage caps in parallel with collector loading resistors not between base-collector. Many say this improves a sound alot.

If you can't put A to A and B to B then you are right they should not try this project. The Miller caps work fine where they are but if you wish to move them that is what this is all about. Having a place to start and doing it from there your way.

Hmm. . . Funny how that's what they all say.

Try to place your post in the threat Single or dual differential?.
It is an ordinary amp with two differential input stages. One thing is unusual - the way of transistor drawing. At the first glance at the schematic in black I suppose that you should place your post in TUBES section.

Doing some mental gymnastics to untangle the spagetti it appears to me a highly generic amplifier with symetric topology. It looks like it came out of a textbook.

Default Exporting Autocad Schematics

You can export AutoCad files as *.wmf, then put the wmf in a power point sheet, and export the power point as jpg or bmp. Not a direct conversion, but can be done in minutes.

Or you can export it a bmp then convert it to a gif, as I did. And it was done in minutes.
