Illuminati (13th Degree)

Nelson has a good article in this months issue. Uses high current N-channel JFET's.
The 3875 is the basis of Brian GT's and many others kit. I have one and they sound pretty good. I tried the stock unit and the modded unit and the mod sounds better. I use a nice Hammond toroidal trans and plenty of capacitor.

You might want to check out the AEX article since it deals with a very different and supposedly arcane topology. Nelson claims it produces the same specs as a triode amp. No one is doing those so it might be interesting.
