Just feed them on the grids through a pad. The glass versions (large
version) will easily run 45 - 50 watts out with convection cooling. I
ran a pair that would do 90 - 100 watts our on HF CW all day without
breaking a sweat. How much more the elements would take with the metal
jacket in water? I don't know. IMD?
Paralleling 6L6s might not be economically viable nowadays as those
suckers have become expensive. I have a Fender, super twin Reverb that
uses six, 6L6s. It was cheaper to buy a new comparable SS amp than
retube the Fender. I've forgotten how much music power it ran, but
popping a low E string while standing in front of the amp would snap
your pant legs against your legs. Monitored with headphones for hearing
protection with that amp.

That's been done with 6AG7's but a 6L6 won't work in GG because it has an
internal connected beam forming element/suppressor.

If you can get some metal 6L6's for a reasonable price at a flee market,
you can turn the amp upside down and place it in a large pan of water
and
really run some power to a bunch of them. A true HB water cooled amp
with
a very low plate impedance and low drive requirements.
