It's connected as a triode in the schematic, too bad the data sheet doesn't cover that operation. But with 600mw output in pentode, you can bet on less in triode, which would be too little for an output stage, probably.
Sometimes I wonder why nobody builds a reverse logic amp, like a 45 driving
3 5687's in parallel or something like it. It's often said that it's the driver that gives the sonic signature of an amp, if so, then why not?
Ok sure, DC on the 45's filament (as a driver) but then the output stage should be quiet, even on very sensitive speakers.
Someday I'll come back to my box of 10's, and try a 10 as a driver, it's been done already by others.
