I think all of them are AB, but the older ES model was closer to class-A.

It is strange (and surprising isn't it) how small the heatsink is. According to my calculation the bias is close to 1A. Attached is a picture of the Schnell (2 pairs, not Sankens).

The TSSA doesn't have the nasty clipping.

Any thoughts on that ?
The effect of regulated supply for the front end is very very good. Imo you can avoid the complexity of the front end ccs and cascades and replace them with BJT regulator (2 volts drop in my case). I prefer it that way, without the complex ccs which adds a little (after the regulation) but seems to substract something from the sound. May be different story with different builders and ccts.

In my fetzilla I use 100R & 4700uF in each rail.

This also works very well also and gives good PSRR - may even be quieter than regulators

At heart I'm a Luddite

What nasty clipping ?? I happen to have repaired a Stark for a friend, it clips perfectly even without the clipping module.

Just recieved some interesting info regarding audiolabor, its designer is Christopher Schürmann who is responsible for the design of the Soulution. That explains many things. The Soulution is regarded by many as the best solidstate amps ever made.

Back panel of the Schnell is an 8mm aluminum plate, thermally coupled to the solid square bars.
Outer shell is an alloy tubular with 3mm wall thickness, pressed to the framework with bolts (the back panel plus square side bars have threaded holes in the bottom side), >350 square inch total exposed surface.

Fetching half of the MSRP, more than two decades later, likely means they're still much sought after amps.
Tony Stark would have been proud.
