Default Class-T with Tubes?

Has anyone tried to use class-T technology with tubes as the power output devices? It dosn't seem that there should be anything wrong with this idea except for the power limitation.

Hi !

I believe that it's pointless to try tubes as outputdevices in a PWM
design. As the outputdevices are switches only, you have no
audiophile advantage from tubes. This means, it only matters
how fast these devices can switch. Class-D designs with tubes
have been tried in the 50s/60s, and discarded because these had
even worse efficiency then analog designs.
Typically, mosfets are designed to switch...

Thanks for your thoughts. Where did you find the info for the circuits using tubes? I'd like to take a closer look and see what their results were and maybe if using some of the new chips might improve things.
