So I've been looking at a bunch of tube/solid state hybrid dynamic amp schematics, and every one of them is some form of bad, or really bad. (one person/ex company in particular)
Low voltage plate, capacitve coupling of a high impedance source into a low impedance, poor balance etc.
There had to be a better way. true balanced input. dc coupling. low impedance output. no feedback. proper use of a tube (pure transconducance) etc
so I came up with this, work in progress. 4 x 3 inches

Walked in own beach chair and supply of Chilled Usual to add the finishing touch.

Well, it was Tuesday, and the menu is in Portuguese, but what the hell. There is a wine store here, and they invite some winemakers to demonstrate their wines in a harmonized dinner, and it was Super! Too drunk at the end to take pictures of the grapa´s, very beautiful bottles.
Wife got mad at me ´cause I first tried the food and only after took the picture. Dessert almost did not survived until then.

i highly recommend you doing a diy-t2 as your first amplifier. More than one person has done this. If you survive you will learn a lot
less dangerous is the supersymmetry dynalo with the golden reference power supply
then the current feedback amp balanced or single ended with the golden reference power supply
more challenging is the uber2 amp
