Tube Question for Audiophriends

Does anyone know anything about the Siemens E280F super triode? It's featured in the Aries Cerat "Genus" amplifier. How does it compare with 300B and other SETs?

That's a pentode. Its a signal tube, not an output tube.

This amp uses 813s for the output stage, so perhaps the OP is asking a question about that?

I may have been confused by the website language--maybe you can sort it out? It reads like this:

“The Genus Integrated…is a small stereo SET amplifier driving a bigger stereo SET amplifier in one chassis.

The input driver stage is a small 0.7W SE amplifier built around the Siemens E280 F super triode and is loaded with a […transformer]. This single tube stage offers maximum linearity and bandwidth for maximum transparency.

The small SE amplifier uses our proprietary AC link coupling technology. This technology uses the secondary winding of the first SE amplifier to modulate the biasing circuits of the bigger 813 tube output stage.

The two 813 directly heated triode tubes use [triple passively treated filament PSUs].”

But really, over the last few years I've never seen this tube discussed on Audiogon, so I wonder why.
