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.
