810 Tubes for Audio Modulation ? ? ?

After a full day of experimenting with a variety of grid modulation
techniques, i'm ready to scrap it and go for some serious high side (plate
modulation) to get some decent audio
quality for my dual 833A VTTC.

I already have a nice RCA modulation transformer with built in spark gaps
etc... (which I think was even designed for the 810 tubes) but was wondering
if the 810
is a decent tube to begin with or should I invest in some 833 tubes???  I
already have (2) good 810 tubes that were given to me.  Obviously i wouldn't
be able to run
at the power levels the 833A VTTC could handle, but i would run at lower
power levels.

What are your thoughts?

Thanks
